Hanging Tooltips solved! It appeared to be that an active button remained in that state when another region/editor became active. It then kept the button-activate state, and therefore also the optional tooltip. This only happened on fast moves, when a mousemove event was not passed on anymore to the previously active subwindow. It has been solved with a new notifier (SWINACTIVE), which gets sent on new active regions. The screen listener then calls uiFreeActiveButtons() to find out if buttons were still active somewhere else.
