I am having exactly the same type of problem. It is only happening on my new mouse which came with a IIfx. It has the little flip open hole instead of the old twist type. It also has the long thin rollers inside along the ball. I think something is wrong with the way the ball is seating on these rollers (the long ones) but I can not figure it out. It seems that cleaning the rollers helps, but the problem returns almost immediately (within minutes)! I suspect that there is something inherently wrong with the design of the new mouse but I have absolutely no evidence other than the fact that my older mice (3) have not shown this problem. I should also note that my environment is not sterile, so the rollers do get dirty on a regular basis. tim.

My mouse pointer recently started making small, unexpected jumps horizontally when I move it. I've cleaned the rollers inside, changed the mouse pad I use, checked for viruses, and can't think of any changes to the inits I use. Anybody seen anything like this that can explain it to me? Any ideas about what else to look at? More details: When I move the mouse around at moderate or high speeds, everything works fine. But when I slow down the pointer will occasioanlly jump anywhere from 1/8th to 1/4th of an inch as I move left and right. The pointer never jumps vertically. The problem is most noticable when I try to make fine motions such as selecting a single letter in a word processor, trying to click on the close, zoom, or resize boxes of a window, or in drawing programs. It seems like sometimes the jump occurs when the mouse is not even moving, but just after I've move it a very small amount horizontally at slow speeds. System configuration: IIci, 5Meg, Internal 40Mb drive, Apple Portrait display, regular keyboard, no nubus cards. System 6.0.5 with system heap enlarged, Multifinder and a few inits that have worked fine for months. Tom McCabe tmccabe@cs.washington.edu

[more description of problem deleted] I had a similar problem with a mouse on a IIcx. No problem, it was under warrantee, so I took it in and had the mouse replaced. The new mouse was of a slightly different (older, I think) design from dealer stock. It too began exhibiting symptoms of "jumpiness". Cleaning helps only for a few minutes, in fact, merely removing the ball and replacing it seems to help for a few minutes. I finally solved the problem by buying a "Little Mouse" (optical jobbie) from a mail-order place. That mouse has only been around for a month or so, but so far no problems. However, I've seen this mentioned on the net before, about three months ago. There were a half-dozen or so complaints of the same problem, all with cx's I believe (though this was before the ci price cuts). I can't help thinking maybe there's a real problem out there hiding somewhere in Apple's mice, system software, or ADB hardware. How many others are having this problem? --Chris (kempkec@mist.cs.orst.edu)

I've cleaned the rollers inside, changed I know of 5-6 cases of this on mice that came with IIci's in our company about 5-6 months ago. The s/n of my offending mouse is AP022878C25. I was told by an Apple certified tech that this is a know problem, that it only happens to the horizontal axis and has to do with some bad pots. It is covered under warranty.

If you take out the mouse ball and move the roller with your finger everything works smoothly, but in normal operation the mouse keeps jumping around all the time. If anyone has a fix, I'd sure love to hear about it. Dan Pleasant [Standard Disclaimer Goes Here}

Actually I think that the comment earlier about the logic board being the thing that is going south may be right. Last night, I left my mac on, and the heat in my office went almost off. This morning my office was about 60 deg. Still in operating range supposedly, but my mouse then acted really fried. I could not get it to move right hardly at all. I recently started using Maxima - a product that lets the MAC see more than 8Meg of memory (while i wait on 7.0...:-( ). That about dates the time that I started having this mouse problem. This is a shot in the dark... but anyone else have BOTH mouse trouble AND use Maxima? ---jon---

I had the same problem, and posted to this net about it. There are at least *four* different designs of mouse. The one with my IIcx failed at about 6 months. I got lots of advice about cleaning, etc., and brought it to an authorized Mac dealer. The dealer *did not mention* to me that it was on warantee, and tried to sell me a new one (over $100), saying I could get something for the the old one in trade (right, the dealer would have just sent the old one back in to Apple for a freebie new one for himself). The solution was that another authorized dealer took the old one from me and replaced it with a new one of a different design. No problems. I just got a IIsi, and, sigh, its mouse is of the design of the one that failed on my IIcx. Now, at least, I will know which dealer to go to. -Chuck - Chuck Hoffman, GTE Laboratories, Inc. | I'm not sure why we're here, cah0@bunny.gte.com | but I am sure that while we're Telephone (U.S.A.) 617-466-2131 | here, we're supposed to help GTE VoiceNet: 679-2131 | each other.
