I'm having a peculiar problem on my Mac IIcx. All of a sudden, when I move my mouse, the cursor tends to jump around on the screen. It doesn't jump very far, but it does sometimes jump towards the top of the screen when I move the mouse so that the cursor should be moving to the *bottom* of the screen. I first suspected a virus, and I have Gatekeeper and Gatekeeper Aid loaded, so I thought I was safe (I have the latest versions of both except that I have GA 1.0.1 because I suddenly suffered several system crashes with 1.0.2). To be sure, I ran Disinfectant 2.1, which found nothing. I rebuilt the desktop, and even rebooted from a locked floppy. In all cases, I have the same problem. I'm fairly certain that it's not a virus, and that leaves a "hardware problem". Has anyone else encountered this problem before? Is my mouse on its last legs (it's only a year old!). Any help, suggestions, condolences will be appreciated. Please respond via email. Thanks! -Eric Feigenson ericf@zurich.ai.mit.edu

It was fixed by replacing the mouse. -- ____________________________________________________________________ Have a day. :^| Murat N. Konar murat@farcomp.UUCP -or- farcomp!murat@apple.com

How much does it jump around. Mine started jumping a little. I took the mouseball out and found goobers on whatever-you-call-them silver things that the mouse rotates against. I guess it made a bumpy surface to rotate against. Joseph Judge joe@cblpf.att.com (Eric Feigenson) writes: > I'm having a peculiar problem on my Mac IIcx.

If you remove the ball, there are three rollers. They should have a smooth surface and be of a uniform color. If they are not, remove the buildup by scraping it off with your fingernail. Be sure to turn the rollers to clean the whole things. You can also purchase a product, Mouse Cleaner 360 by Ergotron that makes cleaning easier. I find that using a mouse pad prevents wax buildup. -- William C. DenBesten is denbeste@bgsu.edu or denbesten@bgsuopie.bitnet

It really does nothing whatsoever to prevent it. I found that even with a variety of mousepads, the buildup just changes from grey to the color of the mousepad. You will still need to remove it occasionally. On the other hand, if the mousepad used above really PREVENTS the buildup, I guess I need to switch mousepad brands!! :-) Dave Barnhart NCR Cooperative Computing Systems Division 3245 Platt Springs Rd.
