TextEdit not launching in Yosemite upload
I have a mid-2011 iMac with a 10.10.1 Yosemite upgrade. My TextEdit app in the dock will not launch, either from the Dock, or from Launchpad, or from the Applications Folder: I always receive a message that says TextEdit is not "responding." I've even found a document that is saved within TextEdit but, again, it won't open because TextEdit itself is not responding. (I'm addressing this question to the Mountain Lion community because I couldn't find a Yosemite community, and I chose the Installation and Setup category because that seemed most apt ... even if TestEdit does appear to be installed already, just not launchable.)
Any ideas? Thank you.
