Desktop freezing
I have had an occassional problem with my desktop freezing ane becoming unresponsive. Nothing on the desktop is clickable and it does not update. For example, if I take a screen show of an app window when the desktop is frozen, the screen show will not appear on the desktop although if I view the desktop folder in the finder the screen shot appears. Can't identify anything specific I am doing prior to it freezing. Anyone else experiencing this and have a solution?
