OK, this is part 2 as I already posted once. I can't get my powermac to shut down or restart. i just get a mouse curser (moveable, however) after the dock and menu bar disappear. I thought maybe it's my logic 7 dongle keeping it from restarting. Nope. Maybe my eye one monitor calibration reminder? nope. I ran activity monitor...nothing out of the ordinary. ....brand new dual 1.8 powermac....2.25 gig RAM. OS 10.4.2. please help...i'll be your best friend. thx.
