You need to look in your user Library/Preferences for the .plist. Hold down the option key while using the Finder "Go To Folder" command. Enter ~/Library. Delete the .plist(s) for the application.
If you prefer to make your user library permanently visible, use the Terminal command found below.
You might want to bookmark the command. I had to use it again after I installed 10.8.2. I have also been informed that if you drag the user library to Finder it will remain visible.
Force quit Finder and test.
Totally awesome response, quick, conscice and helpful, just a quick question to clarify,
When you say"Delete the .plist(s) for the application" What applications do you mean?
My issue is that when I click a file in the Finder and choose "Open With" the dialogue pop up freezes and the finder freezes. It's not a specific application that does it, it's the Finder level "Open With" command that crashes everything.
going to try the sleep function fix next.
Hello Eric and thanks again for the intelligent responses.
FYI I did all that you suggested - the Finder and The Sleep fixes - the SLEEP FIX seemed to have worked. Though I haven't done any work or normal usage, but after the restart, and deleting the Cache and Cookies folder in Library - I was able to sleep and wake the computer without incident.
The Finder.plist however; still no dice. I will try the safe boot version next, but The finder still crashes when I hover over "Open With" in the pull down menu - this time with a blue spinner, then a rainbow spinner. Only way out is to force restart the finder.
Thank you Apple Support Community for the fast and helpful responses. The Finder issue was fixed by simply starting in safe mode and restarting regularly - no idea why, and the sleep issue was fixed by doing permission repair at the start up and deleting those folders in the Library. HAZAAH!!
