tc got a bit working last night, and got into chat. he could get the resolution right, but then the colour changed to 8-colour only and wouldn't allow him to change it. then later he got the colours fixed, but the resoultion was back to the small size and wouldn't budge.
and from what i gathered from him in chat last night, c, he can get to that slide bar, it just appears to be locked, and he can't slide it.
and rai, if what i've gathered is correct, he did use something like the system restore, and that is why it's no longer working properly.
