Sometimes I have a little problem that is of course, no big deal. It's just that every time I maximize after I minimize it to do something, the whole thing went BLACK!!!

I'm not sure if this is a normal and is a supposed problem. But sometimes it's like nothing. Just black and the cursor is standing there. I tried pressing the mouse but nothing happens.

Sometimes if I'm still like around the map to shoot terrorists or CTs, I minimize it, to do my stuff like I said. And then I maximize it again...

Then I try pressing the left mouse, the usp or glock fires. I think this whole thing went black but only the sounds are on. SHIT! I dunno if you guys can understand what I trying to tell you. Errrr, bobba-fat

So live some comments in the section and tell me if this is a normal problem or what.... okay so, bye.
