Has anyone else had this occur after the recent updates? It seems like if I am editing an object on my iMac G5 at work, (GeForce FX 5200 graphics) suddenly my computer will go to sleep. If I manage to get it to wake up again after a few minutes of banging my space bar, if I close the object editing window all is copacetic. But until that occurs it keeps wanting to go immediately back to sleep.
Mac OS X 10.4.8
