Description of the issue

I'm getting some repeated lockups of FileMaker 12 on Mac OS 10.7.3...maybe 5 times a day.
Suddenly all I can do is move windows around...but I can't close them or quit out of FileMaker.

It's happening on multiple workstations and on different databases and different servers. I haven't been able to make it happen consistently.
It seems related to the New Window script step...sometimes that will trigger it.

At first I was using the new Advanced Window Style - Dialog Window (modal) option...because it acts as if a modal dialog is active and you can't click out of it.
But I removed all instances of that thinking it may be related. I also removed any custom menus...trying to simplify but it still happens.
I've carefully updated all versions of plug-ins so they are version 12 compatible (mostly from 360Works)...but some workstations don't even have any plug-ins and are still exhibiting the behavior.

Sometimes FileMaker will go to the first layout in layout order and keep the window on that screen. You can not close any windows.

Steps to reproduce the problem

Intermittent...several times during the day.
