[QUOTE="ronindavid, post: 1153239, member: 45805"] For some reason, my mouse pointer is now skipping/sticking as I move around the screen. Sometimes it just jumps into corner of the screen. It's extremely bad and does it all the time. I'm using the USB Apple mouse that came with this Mac Pro (early 2008). This is NOT a hardware issue. It has nothing to do with the mouse, keyboard it's attached, port it's attached to, or any software installed other than OSX Snow Leopard. That's because the when I boot up OSX from the Leopard disk, the mouse works perfectly fine. I thought maybe I had a virus or something so I wiped the drive and reinstalled Leopard (mouse worked fine), then I installed Snow Leopard and updated (THEN mouse messes up all over again). Again, when I boot from Leopard disk mouse works perfectly again. NO programs have been loaded into this machine. Just the programs that come with OSX. So this has nothing to do with the following...however I've tried all of this: Switch to different mouse, plug into different USB port, plug mouse directly into different USB ports, rebooting PRAM (option-command-P-R during bootup and let it reboot couple of times), resetting the SMC (unplugging power plug and holding power button 5sec), turned off Bluetooth, and did a disk utility check. I'm going to Apple Store tomorrow and will post what they say. [/QUOTE]
Verification
How many occurrences of a n-u-m-b-e-r between "d" and "f" in this example...(sdgs6ngklu3gd#f9%)?
