Ah... I'm not sure I can explain it well. It's supposed to fix misbehaving tool windows, like in old versions of Photoshop.

You need some way of getting the window class for the parent of the tool windows... If you use RabidVWM, try making a hotkey for !alert "^@wc^" then activate it when Flash MX is in the foreground. Otherwise you'll need WinSpy or something.

Anyway, you put *VWMFix ClassName in your personal.rc, where ClassName is the class name you just got. For Photoshop it happens to be "Photoshop", so you'd add *VWMFix Photoshop

I hope that makes some kind of sense.
