Neither do I. htop might show it fleetingly, if I was smart enough to look that is :( > I chose instead to load and print the > images from a graphics viewer so I could have more control over the > process.

See their website. Scissors and > pastepot work grows old in a hurry. True, but the nearest kinko's is probably Pittsburgh, 150+ miles north of here. I don't think there is one in Charleston, 100 miles south.

I will I suppose need that 'sitter' at some point, but so far she is mobile at least half the time. We even made it to Long Johns for dinner last night. A slight improvement. And she went to a visitation in the late afternoon, one of her classmates had passed a couple days ago.
