Just recently, my system has been hanging and is only recoverable by a hard reset. The symptom is a spinning beach ball and a cursor that turns into an arrow when hovering over the dock or the pull down menus yet is inoperable. I believe the culprit is Outlook as that is not opening when clicked or is instigating the problem. The other potential is firefox. I am running the latest version of all software and am Mountain Lion. This issue has just appeared in the last 48hrs. Thoughts/ideas? I would hate to have to delete and reinstall and reconfig office, but will do that if no other options. Any way to check for a corrupted system file or some other cause? Thanks in advance. P.S. Comments to use mail or some other application are not helpful.
