Okay, I'm on a Quicksilver 733 with 1.25 gigs RAM. About a month ago I did a totally clean install of Jag and am totally up to date with software updates, drivers, etc. It has worked okay up until now. Here's my probs: 1. I can't shut down my computer. If I choose Shut Down from the Apple menu I get taken back to the Log In screen and lose my mouse so I can't do anything but log back in. I have to hold down the power button to turn the machine off, which is not good. 2. If I unplug headphones from the headphone jack Jaguar crashes and I am taken back to the Log In screen. This has happened since I installed Jag. I have fixed permissions and have no peripherals connected. What is the deal? I know this may belong in the Mac Help forum we all know more people will see it here. Any ideas?
