I bought a Mac last month thinking my days of computer issues were over. For about 2 weeks now, on and off, my trackpad/cursor randomly goes crazy. It is unresponsive or slow and most of the time it just goes where it wants; i don't even have to be touching any area on the trackpad. I'm a student, so you can imagine how frustrating it might be to try and type a 4 page essay with the cursor randomly highlighting text that gets deleted as you're typing. I'm almost positive it's connected to microsoft word. I didn't notice any problems until I downloaded and installed an update for word (i had previously installed the trial version of office 2008 for mac.) the problem persists even after quitting word and restarting the computer. i think it happens without my opening word, but it's more frequent and persistent when i have been using word. i tried uninstalling it, but i had to reinstall it a couple hours later in order to write a paper. Has anyone had this problem before? Is it connected to Word? Or is it just trackpad issues with the macbook pro? I'll downgrade to a macbook if the problem is going to continue. I forgot to add that plugging in a physical mouse doesn't even help the problem; the two just battle each other. It's only slightly better than trying to navigate with the trackpad.
