Just now I stopped and waited as I was typing this and it didn't happen. As soon as I started to type it did. I have that little norton disk activity utility installed; it shows icons at the far left of the menu bar when disk access happens, different ones for read and write. It shows the disk activity to be reads! I did hear a few where the icon did not show any activity.

Another indication to get off 9.0!

Just typing can do it. No selections, no DoIts, or anything.

VM is off. Better not be paging! (The company paid for this machine and I ordered LOTS of real memory.)

>- You mention the norton disk activity utility being installed. Have you tried this with the base extension set? My test was with the base extensions only.

I've tried it with Norton removed from the base extension set, and no other apps running, but I didn't disable other stuff.
