Erase and install. Just Leopard, iLife '08 and iWork '08 installed. No 3rd party apps. No intensive usage, just setting preferences and checking stuff out... I suppose they're not all bugs, but some are... -- System Preferences > Software Update... option to check daily and not download in the background won't stick. Just reverts to check weekly and download in background. -- System Preferneces > Accounts... when setting apps to automatically launch at login, the Hide option still doesn't work (since Panther, I believe). -- Disk Utility... what's up with the repair permissions function? Slow, or what? -- DVD Player > Preferences... why are these inconsistent with the preference panes in other programs. 'Done' button? Why? -- Mail sometimes fails to quit. Happened 4 times so far. -- Fast User Switching a bit wonky. Sometimes doesn't display the title bar of the account you're going to. More as I find them... Steve.
