No more tooltips after a crash with frozen tooltip

Post by *DrShark » 2019-04-02, 20:13 UTC

This bug has been reported by email to Christian Ghisler, but he couldn't reproduce it so far.
It's rare, I encountered it twice.

It may happen if to switch to TC (in my case I switched from Chrome to TC 9.22,) or from TC (e.g. by launching an app from toolbar that will take focus, in my case I launched mplayer from toolbar in TC 9.20).

So at the moment (or just right after it) of switch to/from TC, crash happens and the tooltip for file is freezing, so after pressing OK in TC's error message it isn't moving or disappearing, even more: that tooltip is now visible on top of other apps (except apps launched in Always on top mode.) Another interesting moment is that the tooltip has strange asian character in a place where it should show properties provided by Explorer. After crash, in that session (until restart) TC doesn't show any other tooltips.

Error message for TC 9.22:

(I also sent WinCrashReport trace of this event, as well as error message similar to above for TC 9.20, but Christian Ghisler didn't find clues to reason of a bug there, so for now I don't see a point in posting that traces here too.)

Screenhots: Because a bug is about a tooltip which also uses wdx plugin, attributes.wdx, I'm posting related wincmd.ini settings:

Code: Select all

[Configuration]
Tips=3
FileTipWindows=1
Win32TipWindows=1
[ContentPlugins]
0=C:\totalcmd\plugins\wdx\Attributes\Attributes.wdx
0_detect=
[HintsCustomField]
0exts=*
0fields=Attributes: S([=attributes.Sparse File]);N/I([=attributes.Not Content Indexed])
This bug may be or not be related to attributes.wdx plugin, or another similar bug with tooltip which doesn't show information provided by Explorer.

Unfortunately I couldn't find any reason for the original crash, sorry. I will have a look at your new trace, thanks.
