Alky what graphics card do you have? seems it affects some and not others. I was affected by it (black radar dots) in a release some time before the 4.12s came out. Using a 9500 pro 128MB 128 bit. Wonder if it's a problem with older cards maybe the 9800 pro 256 bit being more recent won't be affected but a 9800 pro 128 bit will be? I'm just guessing here.
