Script panel window gets overlayed with the HTML panel window

[Avenger]

I am again getting severly hit by a random problem: the sript panel windows are overlayed, so that they are no longer legible. (See image attached.)

I could not discover any pattern, why this happens, so far.

And it happens also with the same site in my local development environment.

Some days it is almost impossible to work (despite browser restarts), then nothing happens for days.

Iam using FB 1.9.1 with FF 12.0.

I remember your first post about this. As Honza already stated there it may be a conflict with another extension.
So I advise you to follow the steps here and try to provide a reproducible test case.
I do not see this using FF 12.0 + FB 1.9.2 on Win7.
