Thank you so much! Uninstalling IntelliType worked.
I was having the same problem with the magnifier. Just yesterday I went through the process of installing the OS and restoring files b/c I installed a new HD. It was starting to look like I had to do it all over again, already. I kept searching for an answer to this issue to no avail. I finally stumbled upon this helpful site, and had to register to give my thanks!
