wow,
i was just about to bring up the thing about the black box, i have one of those now too.
Trying out the new beta 9/20 with the GE beta and thats where i saw the black box.
I tried the steps above and my hibernate procedures was already unchecked. So i checked it, restarted, unchecked it and restarted and did nothing for me.
Im not sure i have the gamma control installed or not, i think i may, did a look for it in the Control Panel but didnt see it or anything in the RR folder. I may have stuck it somewhere else not sure, ill have to do a search for it to make sure.
Well at least u guys are getting rid of it, so there is hope
