>use premiere in the past and have had the program update live as im color correcting. on cs6
1st thought is to ask what is your brand/model graphics card, and what is the driver number?
I have read in other messages that upgrading from CS5 to CS6 required an update of the nVidia driver (maybe ATI as well)
I HAVE A GEFORCE GTX 540M * 2GB INTEL I7 WITH 16B RAM 18INCH LAPTOP
That is half the answer... what is the nVidia driver version?
According to other messages I've read, an update to driver 301.??? was required
