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

In-Reply-To: message from ericf@zurich.ai.mit.edu Take your mouse apart and clean it really good! I had much the same problem with a MacPlus Mouse. I was gonna tek it to be fixed, and before I cleaned it from head to tail (pun intended) It now works great!

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.

I have had much the saem problem, and I took the mouse off, opened it up and cleaned it from head to tail (pun intended). When my mouse did what you describe, I merely cleaned the litttle rollers where the ball was, and that had some, but very little effect on it. When I opened the whole case, I found that somehow I had small threads of stuff, like fibers, or lint wrapped around the little roller bars! I took a twizer and cleaned it all out, washed the ball with a cleaning solution (they get dirty too!) used for VHS tapes, and did the same for the rollers. I also cleaned it with a damp cloth from head to tail (pun again) and made sure the connections on both the cord and my mac were also clean. The result is that I have not had a single problem (probably speaking too soon!) with it since then. And that was about 4 months ago....

It >doesn't jump very far, but it does sometimes jump towards the top of A common cause of this is that the rollers inside your mouse have a coating of wax on them. 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
