If I connect an external monitor to my PowerBook G4 667 (as per the manual) everything works ok until I minimize a window, the Window Manager then jumps up to 95%+ CPU usage and the machine slows to an impossible crawl from then on.<br><br>If I avoid minimizing then everything works fine. Without the external the PowerBook runs fine.<br><br>I have tried the following with no difference....<br>Different monitors<br>Set different resolutions on the external<br>Change the minimize effect from Genie to Scale<br>Update to 10.1.1<br><br>Is anyone successfully running a new "Gigabit Ethernet" PowerBook G4 with an external monitor?<br><br>
