That would suck. Good to know it can be done tho. I have heard of a way to turn off repeats, and I'll look into that before I do any nasty race-condition hacks. I guess the SDL is a good source. (haha pun) Is there anything in dwm that depends on repeats that would be broken if I changed it somehow? I'll get hacking and post a patch if I ever finish. Thanks for your help.
