I trying to figure out if this is a hardware issue or software issue. When waking up my MBPr, about 2-3 times per day it will have lost OS gestures (not Safari gestures). This is fixable by killing the Dock process, but that's ridiculous to have to do multiple times per day. Has anyone else noticed this? I'v tried resetting the PRAM and NVRAM with no success. I talked to someone at the Genius bar who said they can't do anything about it but replace the whole unit (new unit came in, has horrible screen bleed, I'm sending it back and keeping my current one until then). He thought it may be a fault trackpad cable, but I would think the issue would be more consistent if that were the case. Thoughts? I would just reinstall the OS, but I figure restoring from Time Machine will just bring back any software problems.
