Windowed mode chat problem

Ok so when I'm playing everything is fine, but when I go to type a bit of lag happens and the screen doesn't redraw unless i quickly alt tab out and back in again. If i dont alt tab I dc from whatever game im in.
So confused, any suggestions :S

Weird. What are you computer specs (processor, memory, video card)? What OS are you running (Win/Mac/Linux)? How are you launching the game (Steam, standalone client, applet)? What is your Altitude nickname?
