My reoccuring problem with every version after 126.96.36.1990 -

Switching between clocks profiles...
With version .940 I use to OC my card to clock speeds 700/700 along with voltages increased to 1.40/2.20. Then I set up another profile with default clocks (500/500) and default voltages (1.10/1.90). After that I can use auto overclocking or manual oveclocking in games profiles without any problem.
With later versions it is not possible. Everytime I make the same procedure using low level overclocking (driver level doesn't work at all, it never even changes clock speeds), it fails while switching back to default clocks profile. It ends up with blue screens (sometimes with stripes over screen), sometimes black screens,...It si just the same behaviour like when you OC your card too much without increasing voltages.
So the only cause of it I can think of is that ATT somehow switches back only voltages or it switches them first and it results to corrupted screen. Another proof of it is that when I make two profiles using voltages not so different (e.g. 1.30/2.15 and 1.40/2.20) it switches between them without problem.
I'm always using the latest catalyst display driver (currently 6.12), I have DirectX 9.0c december upgrade, Windows XP Pro with SP2, ATi Hotkey Poller disabled... So I would like to ask you, Ray, if there is any chance you can prevent above mentioned issue in upcoming version of your great utility.
