Problems with Quartz and startup disk


Ok. I've been having problems with OS X crashing. I assume it to be a problem with quartz, because gibberish gets drawn onto the screen. Sometimes the mouse still works as a cursor here, sometimes it's a vertical line or a mutating one-pixel point or something. Odd. The other thing is, the startup disk won't stick. I set it to start up to my os x disk, but it never does. The only way to get it to start from it is to hold down option at startup and manually select the disk. Any ideas? I didn't have either of these problems with the public beta.
