Cindy:
And optical mouse may improve you're mousing ability, and is something all cat people should have IMHO. Mainly because of having no ball to roll up loose hair. I would also recomend a wireless one, logitech makes a very nice, but expensive, recharable wireless one. But the cheaper ones will still be nice for you. The one thing I will warn you about is dpi! Be very cautious when you see a 15 dollar mouse, read the box and find the DPI if its not over 600 you wont be happy sence that is what you're having issues with

The eye refresh's based of a dot per inch method the faster the refresh the more movement is recorded. The one that Michelle linked is 800dpi

however if you can use the program listed below untill you can save for this:
http://www.tigerdirect.com/applicati...p?sku=L23-6158 you might be happier

it has back and foward buttons on the thumb, page up and page down buttons above and below the wheel, and a recharable stand. Wireless so kitty wont think you're trying to play

HOWEVER, from reading your post it seems that this isnt an issue right off the bat for you and sence it has crossed with you from machine to machine I would lean more on possible ram bleed. Especially if you still use win98. Memory, especially RAM has a tendency to not refresh, ie when you load a program, then close it, it ramins resident in your RAM for a period, slowing your overall thruput or swap ability. You can at least try this theory for FREE

No I am not part of this software, no i am not trying to drum up usage for this software. I am a computer tech by trade and this is what i use

Because it's free, simple and fast.
I think you should still buy an optical mouse, but reading your earlier posts this might be a viable alternative until you have the funds

BTW hi, i'm new to the boards and a recently inducted cat person: Two 2 month old mynx/taby boys.
