My mouse has been acting very wacky for the last couple weeks. Here's the scoop:
When I click on something that needs a single click to open, more times than not, it opens two instances of a program (e.g. Outlook, Word, Acrobat Pro) or websites. When I copy and paste, it will paste two of stuff. Selecting text, etc. is a real PITB too - selects too much, or not enough. Oy.
That's just a few things I can think of off the top of my head right now. It is darn irritating!!
I have a USB MS Optical IntelliMouse, and it is less than a year old. I tried disconnecting it and reconnecting, slowing down the double-click speed, etc. Still has a mind of its own. Also scanned my computer for viruses, and nothing was amiss there.
Any ideas?

(ARG - just now I clicked to add the little emoticon, and wouldn't ya know it - TWO popped in there!)
