I have an Apple Cinema Display with a MacPro. My monitor has blacked out for a couple seconds. Comes back when I move the mouse or hit space bar. It just started happening after the latest Apple update.

 

This has also happened to my husband several times in the past year. He's on a newer Mac Mini with a newer Cinema Display.

 

Any ideas?

Mac Pro, Mac OS X (10.6.8)
