Thanks Rene and Stephan! I took Rene's advice and it worked! (at least for the bring to front feature so far)... I declared the function prototype in my .cpp class, linked to libtracker, and called the function directly on the mouse up event, and viola ... hidden app is activated. If you all could give me some general direction, I would not mind trying to write a patch for BRoster. The private API caveat will have to appear in my release notes I guess :) Thanks for the quick help! Regards, hey68you
