imac, 20", running 10.5.8 Using any mouse (not mouse specific)

There have been some strange things happening to the imac lately.
Some examples:
-in any browser (camino, safari) in Google maps for instance, placing the mouse curser in a map window, it'll zoom right down to the closest level. When I try zooming out, it zipps right back in.

-in Aperture, while viewing a full screen photo and (using the keyboard) hitting the next arrow, it'll flay though ALL the photos instead of just the next one.

-in Garage band, when trying to move (drag) a track in the timeline, it shoots back to wherever it wants to.

-in Simms 2, the pointer disappears, menu bar flashes on and off, and the main view window spins (looking at sky, ground, up, down left right) all on it's own.

This issue doesn't seem to be application specific, and I've tried different mice. I've run disk repair (and permissions etc) and run FSCK. will shut down and/or restart and the problem may be gone for a few hours, but keeps coming back. The imac is backed up with time machine.

Any suggestions?
Should I erase the drive and restore from Time Machine?

(I've resisted going to Snow Leopard because I'm not sure Simms2 works with it)

Well the browser and Google Maps problem indicates a stuck scroll wheel. If this is happening with multiple mice, then it is software related. Have you tried simply changing any of the Mouse preferences to see if it makes a difference? Making any sort of change could overwrite the corrupted settings and fix things. You could also try deleting the Mouse preferences.

Do you have third-party mouse software installed (Logitech LCC, Kensington, etc.)? If so, try uninstalling that (if you downloaded those installers, they should include uninstallers in the downloading .dmg.

I have a logitec and apple mouse, and the problem happened with both. I tried resetting the PRAM yesterday, and so far, in all applications where I had problems, it's working. My fingers are crossed.

How funny. I just "solved" a problem with the PRAM update.

But I'm on Snow Leopard and installed the graphics update...hmmm.
