Minimizing Windows Locks Manager

I have a weird problem that occurs on all computers and I can't seem to find any information on it. Can someone please confirm it is an issue? V1.3.0206 running on XP fully patched.

Steps to Reproduce 1. Open Manager 2. Open Suppliers Window 3. Open Customers Window 4. Minimize Suppliers from behind Customers

This causes the entire Manager program to lock up with focus flicking back and forth between the two windows. This happens for any Windows within Manager.

Have I got some weird setting configured or does this happen for everyone?

an olide but goodie. happens here too.

Thanks for the feedback. I wasn't watching this thread and thought no-one had posted. I haven't reported as a bug but will do when I get a chance.
