It's true that I have issues with my ATI drivers. The newest drivers don't work for some reason, my graphical card is about 5 years old.
( Common problems with my ATI drivers: crash GPU accelerator, random reboots, system freeze )
Those problems are the reason I don't use the newest driver, but also not the oldest drivers.
I was planning to buy a new one though, maybe then the problem will be solved.
My other computer doesn't show a green line, so I guess the problem lays in the driver.
Thx for the info, I never thought the problem could be in the driver.
