Mouse cursor moving on its own

My mouse cursor keeps moving by itself; it darts quickly across the page, usually on a diagonal. Has this happened to anyone before? I don't download much, expect for torrents for my music...and I stream videos. Other than that I just check email, facebook, etc. I don't have shared internet connections or anything. Could it be the mouse, a hardware problem versus a software problem or virus??

Thanks for the help!

iMac, Mac OS X (10.5.8)

Hi Andie


Clean the optical sensor, check for a dust bunny, hair or other crud.....


Try a plain matte finish mouse pad.....

Could you possibly have your keyboard mouse movements turned on in your Universal Access, under the Mouse tab, in System Preferences, and maybe have something pressing down one of the diagonal cursor movement keys on your keyboard?


If so, the keys j, l (L), 7, 9 keys are the diagonal cursor movement keys.


That's one possibility... Just throwin' that out there..
