Hey Jay,
I had two lockups within an hour today. That's a first. I'm running OS X 10.4.7, with Logic Pro 7.2.1, so I wonder if it could even be platform independent. I know I didn't have anything like this until the VIs got on my machine; the (very) rare kernel panic, but not complete lockups like this. Very strange. The first couple of times it happened I kind of suspected RAM, so I bought some new stuff and everything seemed okay, until today. Frustrating. I sure hope this isn't to do with Stinkrosoft. That's got to be the most infuriatingly bloated copy protection on the market...
