    Can't turn off GPU acceleration

    Bongboots Level 1

      I have tried GPU acceleration in the past, but it wasn't enabled for my Radeon HD 6950. Ironically, today I found it was, and turned it on. LR was soon freezing in the Develop module, so I went to Preferences to turn it off again. I've tried several times, but it doesn't uncheck, just freezes! I tried rebooting, but freezes again while trying. Is the only way to delete the Preferences file, and if so, where is it?
