[BUG] Some keys don't work if a "Not Found" dialog

[alinnn]

Steps to reproduce this:

1. Start TC
2. Select a text file and press F3 to view it
3. Search for a text that is not found in the text file
4. The "Not Found" dialog appears
5. Don't press the "OK" button in the "Not Found" dialog and switch to TC's main window
6. The "TAB" key doesn't work and maybe other keys, too
7. If I open a new viewer window, the "ESC" key doesn't work in this new window

This bug occurs in TC 7 beta and also in TC 6

Confirmed.

This is a known problem, unfortunately cannot be fixed (search the forum, Chris explained that once or twice). It's a problem in Windows.
