Thanks for the info! The "unknown tokenizer" error is not relevant - it appears because the DB is opened not from within CN.

Is there any chance you could send the crashing .db file to me? It would ease the debugging task enourmously! But of course you don't need to do that if you have any sensitive data in there.

Thanks for complimenting the icons)

Regarding the vertical arrangement, I have been advised  that it allows much easier comparison of the dates.

Could you please download SQLiteSpy from here, load your suspicious .db file into it, run the following command:
PRAGMA user_version;
and tell me what it returns? Thanks!

Seems that I have no flicker when that happens. Well, redrawing is necessary because the size of the label changes and it may lead to control repositioning and even whole dialog resizing (if your dialog has minimum height).And I didn't was to reserve that height to keep the clutter to a minimum.
Is this flicker irritating? If so, I'll investigate further.
