TActionMainMenuBar starts 2 Threads when clicked for the first time. They
stay active until the application is closed.
Who knows why?

Most likely what you are seeing are the threads used to process the Window's
sndPlaySound API which is used by the ActionBand menus to play menu sounds
asynchronously. The ActionBand menus themselves do not use threads.

Hello Steve,
Well, if sndPlaySound( ) opened threads, they would not belong to the
Delphi-application, would they?
I set all sndPlaySound calls in unit ActnMenus to comment and still the 2
threads appear (visible in Task Manager).
So the miracle seems to persist..
besides- an old question again:
The ActionToolbar does not always reset the MouseOver-selection, when the
mouse leaves the symbols. This effect seems stronger on slow computers. Same
effect occured with your preliminary version in Delphi 6.
Got an idea?
best wishes, Achim
