[Beta] Some bugs with Thumbnails Settings dialog

[Sheepdog]

1. Open TC
2. Click Configuration -> Options -> Thumbnails
3. Don't change anything - click OK or Cancel
4. Open a SECOND TC instance
5. Click Configuration -> Options -> Thumbnails
6. Click in the box Copy/delete thumbnails with files
7. Click Apply
8. Close the FIRST instance of TC
9. Open a NEW instance of TC (it will be unnumbered)
10. Click Configuration -> Options -> Thumbnails
11. Go to the SECOND instance of TC (marked [2])
12. Click in the box Copy/delete thumbnails with files
13. Click Apply

This way I cannot reproduce it.

Thanks for providing the exact steps to reproduce this error! Indeed TC was trying to aquire a database lock (via a so-called Mutex object, giving MUTual EXclusive access to the thumbs database). This fails with a timeout of 10 seconds because the mutex was not released in another thread. It was quite difficult to find, but easy to fix.

Hmm - I just tried it again with a complete virgin wincmd.ini - and reproduced it.

Anyway it seems that Christian has figured it out

Hmm, one probably needs to use the thumbnail database to reproduce the error.

Yes, this is correct, it only happens if you have set a thumbnail database name (even if the thumbnail database has never been used).

Seems to be fixed in TC 6.54pb2 !
