I'm on Parallels Desktop 6 on a Mac OSX 6.7 in Windows 7 64-bits running Photoshop LightRoom 3 64-bits. The problem is that LightRoom displays images as grey squares, sort of place holders, no color and no image details. I have no problems with LightRoom when in Windows 7 32-Bits. Anyone on this Forum has this problem ? Any suggestions how to solve this problem ? Thanks.
