"Character" pop up window opens every few seconds
In 21 years using a Mac, I've never had this problem.
Suddenly, last night, the "Special Characters" window (option + command + T) started popping up on the screen. It appears over every software I have open and slightly delays use of that application.
1. I clicked (option + command + T) in every open application
2. I ran MacKeeper to look for bugs
3. I rebooted the computer 3x
4. I looked for the (.plist) file with 'character' in the name and it does not exist
5. I opened and closed each application to see if I could find the application it's occuring in (still pops up when I have no—zero—applications open)
6. I cleared out the history & cache in Safari
Yes, it's driving me insane! This iMac is my primary work tool and I'm unable to conduct my regular work day while this window continues to pop up.
I feel like I need to clear off the "cache" for the computer and need direction before I start deleting .plists, etc.
iMac, Mac OS X (10.7.4)
