Ok, I can open Hammer ok and start mapping for a while, but then it messes up. I can't move the camera around in 3d view, when I try to move in the 2d views it just screws up and I can't see a thing, so I have to close Hammer and reopen it. It will work fine after I reopen it.
I'm not sure if this is a Hammer problem or a graphics problem, because I can play CS: Source without any problems.
Anyone got any idea of how to fix this, or even what it is?
Thanks in advance ![]()
