A more precisely controlled mouse?
Well, I went ahead and ordered the Logitech MX 1000 before I read the suggestions from ehBeth, fishin' and boomerang.
The mouse was cleaned a short while back.
Not a dumb question, at all, BTW - it's awfully easy to forget little maintenance details like mouse-cleaning. And no, I didn't use the magnetic lasso tool, although it is available on Elements. I am a total beginning beginner.
Walter - the 610 is still available and I read some of the Amazon reviews; mostly favorable, though a couple of pretty unfriendly ones. I looked at the reviews of the 1000 and was greatly impressed.
So now I'm waiting for the Amazon free (but v e r r y s l o o w) shipment. But slow saves quite a lot of money as against Staples $79.95 with free next day delivery. I can wait. But I am greatly looking forward!
