For unknown reasons, my database often gets corrupted; a few second after starting IQ, it no longer responds (I have waited up to about 10 min). Sometimes, if I restart a few times, I can get IQ to respond (after a long delay).

Repair doesn't help, but rebuild fixes the issue.
The problem is that I need to get to the rebuild screen very quickly before IQ stops responding. I usually have to try a few times.

Currently, only the active (problematic) database can be rebuilt.  Is there some way to open a blank database and then point to the database that I need to rebuild? Maybe add as an option?
