    Hi all,

    I've received my MacPro (Quad, ATI 5770, installed a Vertex 120GB and 8GB RAM myself) last week, and just started up Lightroom for the first time.

    I've run into a strange problem. On most occasions, when I adjust one of the sliders, the photo blinks to black. Seems like it's some sort of graphics driver problem, although it works just fine when playing Starcraft 2.

    I've made a iShowU HD capture. You can check it out over here (.mov, 643KB)

    Does anyone have a solution? This is driving me nuts...

    Strange, I have the 6-core + 5870 and have no issues, I spend a LOT of time in LR and I would have noticed.
