Phil, you sound like you are too out of date with the Apple operating system (10.5.x). I am running 10.7.5 and don't have the symptoms you describe. And 10.8.x is actually the current OS.
Am not sure of this, but it sounds likely, especially since you indicate you have applied all Apple software updates.
