TC shuts down when trying to overwrite file and then cancel it with Esc

[Sektor]

Here are the steps to reproduce situation:
1) Have two files with identical names - say, C:\Folder1\File1.txt and C:\Folder2\File1.txt.
2) Press Ctrl+C on the file in Folder2.
3) Go to Folder1.
4) Press Ctrl+V. The Windows dialog appears saying "The destination already has a file named File1.txt".
5) Now, if you PRESS and HOLD Esc, TC shuts down after about 2-4 seconds.

I could reproduce it, but only in Win11.
Here is the report from Event Viewer:

Not confirmed.
Tested with TC x64 and x86

I cannot reproduce this. Tested wih 32bit and 64 bit TC 10.00 under Windows 7 and Windows 10 21H1.

So it is probably a Windows 11 problem as umbra points out.

Interesting that the Windows 11 version of DUI70.dll has version: 10.0.22000.1 and not 11.something, but I guess that is Microsoft in a nutshell...

It's Windows 10 Home 21H1 19043.1081 x64
TC is x64, dark theme, regular user mode

Its exactly my environment and as said I can't reproduce it.

Except for the Dark theme - it was the same I tested with - I have now tried with TC in Dark mode, but still no crash.

Maybe this info will help: I installed Windows 11 but then got back to Windows 10. Maybe this is the reson?

@petermad @Horst.Epp @umbra
Also tested on another computer: Win10 Pro 21H1 19043.1081 x64 (no Win11 installation), TC x64 regular user mode.
Same thing!

I can reproduce the problem, but it seems to be a bug in Windows itself. It does not need to be in dark mode, it also happens in normal mode. However, it doesn't always happen, only when a Windows dialog flashes shortly on the screen.

The dialog shows:
Title: This cancels all transfers in progress.
Text: Are you sure you want to cancel all transfers?

So what I think happens is that the pressed ESC cancels the dialog multiple times.
Interestingly, I get the same dialog in Explorer, but it doesn't crash...

Total Commander 7.50 Public Beta 4 works fine.
Total Commander 7.50 Public Beta 5 (pre1) doesn't.

Probable cause:

31.05.09 Fixed: Copy+Paste (Ctrl+C/Ctrl+V): Execute 'paste' in background thread because it hangs on Vista when pasting large files

[ghisler(Author)]

Sorry, I can't move past back to the foreground thread, it can cause the program to hang.

No one is asking you to. But perhaps you can now better pin point the problem and perhaps fix it.

[ghisler(Author)]

I have tried it, when I call the exact same functions from the foreground thread, the error doesn't occur. Unfortunately this has other downsides like possible hangs, so I don't want to do this.

I tried not closing the background thread, but that didn't help either. The error occurs in a completely different thread (created by OLE2) outside of my own code.

Is it possible to prevent that TC exits?
