I get this weird OS dialogue window when trying to remove locked items in the OS or system prefs (when removing one). Any idea how to fix this?
I'm having the same problem. I found this article on how to "Clear Font Caches & Font Databases in Mac OS X to Resolve Unusual Font Problems."

Well good to know now. I updated to 10.11 and it cleared the issue up at the moment.
