Has anyone else had one item overwrite another?

OK, here's an extra buglet that might be related.

I still had 'Reload tabs from last database session' turned on. I just closed all tabs except one before closing the program every night. So I did this last night - and this morning the program opens with three tabs I was working on before. Ie the 'reload tabs...' feature doesn't work consistently. The program was shut down, and Windows shut down, with no problems.

(The contents of all 3 re-opened tabs was present and correct... haven't found anything wrong so far.)
