Bob Bob, I saw someone ask the question but I don't recall seeing the answer, but it's possible I missed it, so I'm going to ask again: When the space is dropping, what does Console say at that point in time? What does Activity Monitor show -- in the processes window, click to sort by CPU (what's using the most?), Virtual Memory (is there something showing 40GB of VM?), etc. For example I see that my kernel_task process is using 1.77GB of VM, and I know that if I restart my computer, I usually gain two or three GB back. Safari comes in second with 1,015.54MB of VM. What does/did yours say? Any clues there? Do you have any Safari add-ons/plugins? ~Linda
