I installed the new version of RDTabs the other day. When I start it up, the menu bar is not drawn correctly - whatever is on the screen behind RDTabs appears where the menu bar should be, but no menu. If I minimise and maximise the window, the menu bar doesn't reappear, but if I move the RDTabs window, it does. If I bring another app to the foreground without minimising RDTabs, then bring RDTabs to the foreground, the area where the menu bar should be shows whatever was on the screen before RDTabs came to the foreground !!!

That's very odd. Does this happen in other apps? This sounds like a video driver issue with overlay graphics.
