I am running my code on Ubuntu 10.04.2 LTS (Lucid Lynx), 32-bit version. I think you are probably right. Earlier today, I wrote another program with the ncurses library to see how I can go around this problem and it seems that when I resize the terminal running that code, it also seems to not receive keyboard events. So would this be a dead end? Any suggestions? =) _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
