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:

Code: Select all

Total Commander 9.22
Invalid pointer operation.

(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

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.

Cuz we're all in this together, We're here to make it right
