I have to shut down my other monitor to use either GTKRad or Quake3/Gen....other wise it crashes continually on start up...anyway to fix this issue?

Sys specs:
proc: p3 866
mb: ive forgotten exactly what it is...
vid1: gf2 mx400 vid (agp)
vid2: tnt2 model 64 (pci)
soundcard: fortissimo 2
mem:  384mb
running win2k as my OS
drivers are seemingly updated, so im at a loss of what to do now...

Hmm... I know I've gotten Q3 to run before on a dual monitor system, but I can't remember if I ran into this problem or not.  I don't live by that person any more unfortunately to test it out.  The only suggestions I can think of off-hand is to try running Q3 restored rather than fullscreen.  (Set r_fullscreen in your q3config file to 0.)  As for Radiant, that's an odd one.  I'd go with Woodman's suggestion.

Powerstrip might be what you're talking about. Good proggie

Let me know if it works. I intend to try 2 mons if it can be done.
