Every time I open Lightroom I get a series of issues, eventually leading (every time) to a complete lockup, requiring a restart of the whole computer.
Usually LR will run sweetly for a few minutes, then the screen started getting a bunch of artifacts flickering across it. Things get a little choppy. Sometimes it freezes up right then, sometimes it ends up looking like this: http://smg.photobucket.com/albums/v680/ixo...t=lr-error1.jpg (that's a screenshot I grabbed during one episode).
In the end, it always freezes.
If I look at the system logs, I consistently see this:
"May 1 16:18:17 ryMac /Applications/Adobe Lightroom.app/Contents/MacOS/Adobe Lightroom: CGContextClosePath: no current point.
May 1 16:19:09 ryMac /Applications/Adobe Lightroom.app/Contents/MacOS/Adobe Lightroom: CGContextClosePath: no current point.

May 1 16:25:39 ryMac kernel[0]: Graphics chip error! Restarted.
May 1 16:25:44 ryMac kernel[0]: Graphics chip error! Restarted."
The "CGContextClosePath..." series is often repeated for several dozen lines.
WTF? Why did I even buy a Mac if it's going to suck worse than a PC? This is on a 24" iMac, 2.16 C2D, 2gb RAM, 7600GT video card.
Any help would be appreciated, since it would be nice to actually be able to work for more than 5 minutes without having to restart.
