MouseMove in TrackPopupMenu

Hello !

I use TrackPopupMenu to display a popupmenu. Everything works fine, but I want to stop the tracking and close the menu if the mouse if over some other area of the window.

How can I do this ? I tried to use "OnMouseMove" in the window, the popupmenus belongs to, but if a menu is tracked, this function isn't called at all..

Regards

Martin
