In my previous version, I use glut and MFC for GUI development. The previous version goes well in both single monitor mode and dual monitor mode. Thus I think the problem is related with FLTK . My video card is Intel GMA 900 onboard, and my system is Win xp Sp2. _______________________________________________ fltk-bugs mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-bugs
