Have an older 800 mHz flat panel iMac on 10.3.9, whenever I try and throw something away, send email, and a host of other actions the screen will go blue and the desktop will start up again as if I logged out and then back in. I've tried rebooting, repairing permissions, and running the unix maintenance. I also made a second account, logged in with it and it did the same thing, only with the second account it would just log out and kick me back to the login page. The admin account still just logs out/logs in in one motion. Anyone ever hear of this?
