Frequent Crashes in Thumbnail Mode

[ArthurASCII]

One of the great features of Total Commander is the ability to view files in thumbnail mode.

However, V10.5 frequently crashes when displaying thumbnails at 256 x 192 or 128 x 96 size.

Look what thumbnail providers you have.
For me there where TC crashes when SumatraPDF was providing PDF thumbnails.

If you have the K-Lite codec pack installed, it happens when the thumbnails are not square. See this message:

If you don't use it, you can try to find out which file causes the crash, and also which plugin (if a plugin was used).

Please add the following string to the file wincmd.ini, section [Configuration]:
DebugIconThread=3
You can edit the wincmd.ini via Configuration - Change settings files directly.

This is an undocumented option because it makes TC quite a bit slower. So please
remove it after finding the issue.

It will create a file named tcicolog.txt in the TEMP directory. You can go there
via TC command line:
cd %temp%

View the file with F3, scroll to the end and search backwards for:
thumb:
To find the last extracted thumbnail.
