You will need to give us a lot more info; - what version of fltk are you using - what host OS - what tool chain - what window manager / windowing system One thing that occurs to me is that fltk-2 can be slow to start initially if it is loading in a lot of fonts and so forth (it seems to load its fonts differently from fltk-1.x versions). If so, try fltk-1.1 or fltk-1.3 and see how you get on, or configure fltk-2 to use simpler font options. I mainly use fltk-1.3 now, and do not see responses anywhere near as slow as you describe. There are quite a range of performance analysis tools available these days that will monitor your code as it runs and provide details of how long each part is taking; it might be informative to instrument your code start-up sequence and see where the time is really going. My own personal experience suggests that it is rarely inside fltk itself - the time is mainly lost in system and support operations... But without measuring this we can not know for certain. -- Ian SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
