Recently my mac has been acting crazy.  When I put the cursor on something, it jumps away.  If I have more than one program open and am working on one, suddenly it jumps away and all of the open programs are visible at once in small versions.  It takes me 4 or 5 tries to just click a button.

Any ideas how to stop this?

Thank you.

    For starters  it would help to know what kind of "powermac" you have out of the many models out there.  Are you using a mouse or a trackpad?  Have you tried using a different mouse? Have you cheked your mouse sensitivity in system preferences? If using a mouse, what kind? Wired or wireless? If wireless, is the battery good? What surface are you using this on?  As you can see, it helps to provide background with this kind of question...


    The "small versions" thing sounds to me like your cursor is jumping to the corner of your screen where it activates one of the Expose features.


    Frankly with the jumping mouse my money is on a bad mouse or trackpad.

    Thank you.  You are right, bad mouse.  I turned Expose off, which I never use, and it is working fine now.

    Just FYI, disabling Expose it just dealing with a symptom but not curing. The cursor may still jump around, it just won't trigger Expose.
