Scrolling in file list with touchpad, x64 version 8.01

hello_world.c · Post by *hello_world.c » 2012-11-03, 14:38 UTC

On my new Thinkpad laptop that runs Windows 7 x64 I installed the x64-version 8.01 of TC. With the touchpad, there are two methods of scrolling, the two-finger gesture and the up/down slide on the right-side scrolling area. Neither works in file lists in TC but it works in all other programs that I tried. I see the mouse cursor changing to indicate scrolling, but it is not doing anything.

On my older Thinkpad with 32-bit Windows 7 I installed the 32-bit version 8.01 and there, scrolling works just fine using the same method.

Edit: With the scroll wheel on a bluetooth mouse, scrolling works in that version, so it is only the scroll functions in the Synaptics touchpad that are not effective.

Could you try the same with Total Commander 32-bit on your 64-bit machine, please? There are almost no drawbacks to use the 32-bit version on a 64-bit system.

Thank you for your answer.

Yes, it does work in the 32-bit version on my 64-bit system. However, I rely heavily on icon overlays from 64-bit TortoiseSVN which I have to use to make them also work in Explorer. Those only work in the 64-bit version of Total Commander as well, naturally.

The 64-bit version is compiled with Lazarus/Free Pascal, the 32-bit version with Delphi. It seems that your touchpad isn't compatible with Lazarus controls, so there is problably no change to make it work.

Why not just install 32-bit tortoise too? That's exactly what the tortoise makers recommend for this situation. Juzst install the 32-bit version to a different directory than the 64-bit version.

I don't know what TortoiseSVN you have, but for some time the 64-bit version is no longer 64-bit only, but contains support for 32-bit programs too. So you install only one and it works everywhere.

Interesting, so they must have changed it recently...

Sob: I have to use an older TSVN version for reasons that would be off topic to explain here.

I knew about the option to install both the 64-bit and 32-bit clients but I'd rather avoid running two clients in parallel.

Luckily, I found the solution in changing the behaviour of the Synaptics touchpad driver. Apparently Notepad++ exhibits the same problem. The workaround is explained here (post from Joel):

You lose the mouse pointer animation while scrolling, but you get the actual scrolling back. The lesser evil by far.

I wonder what messages the touchpad is sending - TC is using a standard Windows ListBox, so it's strange that scrolling fails with it.

See here:

Apparently, without the workaround it's trying to move the scrollbar directly?

Hmm, but you can move the scrollbar thumb with a mouse pointer directly, so why shouldn't it work with the driver? It must be doing something wrong...

It's weird, but it's true! There is the same problem on my Thinkpad with the 64bit version (all 64bit: win7pro, synaptics driver, tc) as well! I solved the problem by following the answer in the link above.

Best greetings!

Hi,

I just want to confirm that this is happenning to me as well with 64bit version of TC 8.01 on Win 7 Pro (Toshiba Qosmio, Synaptics touchpad).

32bit version works flawlessly.

I have a new notebook with Windows 8 pro x64 now. It has a touchpad from Elantech. I noticed that the 2 finger scroll only works when the Elantech software is running - but then it works both in TC 32-bit and 64-bit.

Apparently the driver of your touchpad has problems with TC 64-bit. Unfortunately I have no idea why, the two handle the scrolling in the same way. Maybe it just doesn't like 64-bit programs. All I can recomment is that you use the 32-bit version of TC.

I had similar issues with a Synaptics touchpad. Scrolling worked just fine in some applications but unreliably in others - and most of those were running with elevated privileges. However Synaptics' driver SynTPEnh.exe runs by default with only normal privileges. Once I changed that, scrolling worked everywhere.
Note: not all elevated applications had these issues and it probably won't help the non-elevated ones

Yeah, I switched to 32bit version to fix it.

The interesting thing is that it works in all other 64bit programs I have (Tested with Opera, Sublime Text, Office, WinRAR). The only program that has issues is Total Commander
