In Flex Builder 3 the project properties panels do something similar.
On the left pane are the options and on the right are a details pane.
The details pane often has it's boxes and tabs misplaced (off screen).
By dragging the separating edge between left and right panes you can fix
some of it.
In some case you also need to wave the mouse, like a magic wand, and the
tabs reappear.
In other cases I can't get to the options in the boxes.
Recently I find that I get a black hole (rectangular) in the topmost
edited file's pane.
If I scroll with the wheel mouse only part of the pane updates.
Once I switch tabs and back its okay.
This hole may have arrived when I added more memory but I can't be sure.
It all sounds like the same kind of problem.
