I can reproduce it - something I discovered since your reply.
1. Exit IM5 while I&A panel displays properly
2. Run IM5 - voila the I&A panel is blank
Interestingly, the F9-I keyboard shortcut will not close the blank panel. Trying to do so just causes the "boing" (error?) sound. So this adds another piece to what now seems to be an actual bug. Maybe this part adds a useful clue.
Closing the blank panel & reopening it solves the problem - not elegant, but it does the trick.

Windows 7 with updates up to date, Dell Studio 17 laptop, IM5 release 150, IM5 DB is on a thumbdrive, files on a NAS as shown in the attachment
