For most of the year I've been having trouble using Acrobat (8) and Reader (9.1.3). They both lock up when I click in a text field. I have to force quit and reboot. Reinstalling hasn't helped - nor, obviously, has upgrading - since I think I'm using the latest versions.
It started around the time I installed iKey by Script Software. I have since zipped those files (as far as I can tell, there are no lurking drivers still hiding out).
When I do touch the text field in either Adobe product, it immediately starts highlighting text from the point where I touched.
