After a recent Microsoft update, all of the "fine tuning" controls in my ccc simply disapeared.
There would be only one screen (display detection etc.) that would appear.
No access to anything else at all.
Sooooooo, I uninstalled it and redownloaded and installed a new one from the ati site.
Now although it show up in my programs list,when I click on it all I get is a momentary flickering cursor.
It won't open at all. Not sure if I downloaded the right one or not,because the list of CCCs and drivers couldn't possibly be more confusing to me.
I went for the one that said 5870 windows7 64 bit.
From what little searching I've done online (at work right now) this seems to be a fairly common problem and I haven't seen any real solutions yet.
