Smooth scrolling sometime is on

[vassapup]

Hello!
There is rare bug that occurs from 10-20 times per day to 1 per week.
The system performance options "smooth scrolling" is off, but it rarely turns on only for a Total Commander window (so, there's no smooth scrolling i.e. for IE simultaneously!) when I just switch between applications.
If there several TC windows are opened and the bug occured, I've even seen that sometimes there is the bag in one TC window and no bug in others TC instances!
When the bug is happened I must turn smooth scrolling on and then off in system settings (OS is Windows XP sp3 x86), this is very annoying.

To my knowledge the is no Smooth scrolling setting in TC.
So you may better search for mouse driver and related tools updates.

[vassapup]

the is no Smooth scrolling setting in TC

Yes, Total Commander uses system setting "Smooth scrolling".

So you may better search for mouse driver and related tools updates.

No. I've had this bug many times on different computers for several years. It is started somewhere in 8.5+.
All this time I thought that other programs are to blame, but now I can definitely say that the TC is to blame because
1) The system setting "smooth scrolling" stays turned off.
2) I've never seen the bug in any other application.
3) Once occured, the bug subjected only TC (and only one window if there are many TC windows) but no other programs.

vassapup,

Does not necessarily mean the bug is in TC.

I can confirm a similar behavior which I've had for over a year now. Smooth scrolling (aka listbox animation) enables itself while using TC. However, on my system it is enabled for ALL windows, not just TC.

So far I've tracked it down to the Lister plugins, though I don't know which one it really is. I played a little bit with their priority (and temporarily disabled some of them using TC Plugins Manager), and the issue hasn't been reoccuring so far. So, I suggest to do the same.

Thanks!

I disabled this plugins in [ListerPlugins] section:
MKInfoLS.wlx
APK.wdx
TCMediaInfo.wdx

and up to now I haven't seen this bug. I suspect TCMediaInfo as a source of the bug.

Interesting. I've suspected a different plugin as the culprit: LinkInfo. Anyway, here's my list of Lister plugins (_detect lines removed):

Code: Select all

[ListerPlugins]
0=%COMMANDER_PATH%\Plugins\LinkInfo\LinkInfo.wlx
1=%COMMANDER_PATH%\Plugins\SynWrite\Syn2.wlx
2=%COMMANDER_PATH%\Plugins\PEViewer\PEViewer.wlx
3=%COMMANDER_PATH%\Plugins\FileInfo\FileInfo.wlx
4=%COMMANDER_PATH%\Plugins\Imagine\Imagine.wlx
5=%COMMANDER_PATH%\Plugins\VisualDirSize\visualdirsize.wlx
6=%COMMANDER_PATH%\Plugins\EventLog\EventLog.wlx

Maybe you use/have some of them as well, so we might be able to track it down further.

I will enable disabled items one by one to check which one is buggy. But it will take days to weeks to test them because I have no idea which exact action cause the bug (it occurs spontaneously).

This if my 32-bit plugins - my 64-bit plugins is a subset uf these.

[Dalai]

The plugin priority/order has something to do with it. Normally I list specialized plugins first (SynWrite, LinkInfo etc) so the other plugins only get loaded when necessary. Since I have this issue I've changed the plugin order - the issue might occur more often or never, depending on it.

A lot of my plugins are set up to only load when forced (id_detect="force"), this way they are only loaded after pressing "4" one or more times.

After enabling TCMediaInfo plugin today to check something, smooth scrolling almost immediately enabled itself. So, I suspect vassapup is right, TCMediaInfo might be the culprit. However, I've had this issue on TC installations that use a different set of plugins where TCMediaInfo is only used as content plugin. Perhaps the plugin messes with the system in that case, too.

Maybe it's caused by a specific Windows control, e.g. like the HTML viewer of the help system causing middle mouse button scrolling to be turned on?

Anyway, I only found a global setting to enable/disable smooth scrolling system-wide...

Wrong thread? I don't see where the HTML viewer is involved here.

Yes, it's enabled system-wide on my systems.

I can now confirm that it is TCMediaInfo plugin that's causing the smooth scrolling/listbox anmiation to be enabled Yesterday I did some tests by renaming all existing plugin sections in wincmd.ini and copying the relevant entries of TCMediaInfo plugin. I loaded a custom columns view which uses some fields of this plugin, and smooth scrolling was enabled immediately upon closing TC. Globally enabled, mind you, which can be checked in any listbox like the list of fonts in Notepad's font configuration, or the list of saved sessions in PuTTY.

The plugin does this when it is unloaded, either by closing TC or executing cm_UnloadPlugins command in TC. It doesn't matter if the plugin is used as Content or Lister plugin. Version 0.7.1 is the last version that doesn't cause the issue at all, 0.7.2 causes the issue only when used as Lister plugin, 0.7.3 and later cause the issue regardless of the plugin type.

I'm going to write a bug report in the according thread in the Russian forum if it hasn't been already reported; currently I'm reading the thread translated by Google Translate, so it may take a while.

To work around the issue without replacing the plugin with another, you can downgrade to version 0.7.2 or even version 0.7.1 for now.

A couple of hours later.

I was about to write my bug report and booted an English language Win7 system, mainly to be able to look up the correct terms in Windows. I tried to reproduce the issue on this system - with no luck. I tried another Win7 VM, but that didn't change anything.

Interestingly, while I was trying to reproduce the issue, it happened twice that the window animation on maximize/minimize (which I have disabled as well) enabled itself. This didn't happen every time the plugin was unloaded, but rather rarely. But it's quite obvious that the plugin has something to do with this, too. So the question remains: Is it worth the effort when XP is affected but Win7 is not? Even more when the issue can worked around by using an older plugin version.
