Since upgrading to OSX 3.9 , my mouse and keyboard constantly freeze. I suspect a conflict, but FirstAid and the CD's Utilies ( AND the consol fsck -y search find nothing.
It MAINLY happened online and/or when using MSWord 2001.
I recently added Firefox and Thunderbird and the freezing got worse ( froze twice while doing this note).
When my daughter logs into her mode, she's getting a crash error message of (Unix style) "Push restart button now"
I don't have Norton or TechTool ( which one is better BTW?)-so many suggestions?
Your assist will be greatly appreciated.
