Are you using TS overlay by any chance? If yes, then turning it off will fix your problem, it fixed mine.
Well that sucks. Double edged sword. Cause if you're like me and need the steam overlay for events, you most definitely need the teamspeak overlay as well.
huh ?! with all the graphics and stuff u do I thought for sure that u would have a second screen
I actually JUST started using a second screen like two months ago. Don't know why I didn't do it sooner!
HOWEVER, Steam window on the 2nd screen doesn't flash when you get a message... which is another SLAP IN THA FACE !!!!
So I gotta glance over every five minutes, or 20 if I forget, and then I have to Alt-Tab out just to respond. And If I'm recording, its ANOTHER SLAP IN THA FAAAACE !!!!!
