Okay that's what i thought, i got this problem once before, and i think CrapShoot got it once. As far as i know it's a bug that we have no idea what the cause is. It's been in Fritzbot for awhile and it's very sporadic (it shows up out of the blue for no real apparent reason at random)
The only fix we found for it is to re-install RTCW. You'll of course have to re-install the patch and maps and such but a fresh install works. So make a backup of some of you're important files and such within the RTCW directory (not you're wolf setting configs though as it may be some wacky RTCW variable causing the problem) but like waypoints, save games, custom maps, etc. you should backup (or move to a different folder until after the re-install)
I wish i could give you an easier fix but this is the only solution to this problem we know of and it does work. On a side note, this would make a good addition to the Wiki FAQ, so i think i'm gonna add it.
Hope everything works out for ya.
