Cant move sliders in ati overdrive tool

[Thomasj]

I just installed a HD2600 pro and in the catalyst control it has an overclock tool. I first had to unlock it and click ok to the warning. But now when I try to grab the sliders to turn them up, they will not move. Any Ideas? They are not shaded out or anything like that. I just click and try to drag them and get nothing. They dont budge

I just got a visionteck hd2600 pro and have the same problem. Are you dual booting OS. What kind of motherboard do you have. is crossfire compatible. does you motherboard have a ATI chipset.

I am doual booting between windows xp professional and windows vista Ultimate. I have a motherbaord with an Nvidia chpset and obviously no crossfire. One thing i do notice is that the gpu clock had 601 on the left end and 601 on the right hand.
