Recently I have run into a problem where the rename shift+f6 and all the menu options are disabled. I can't find any setups that would cause this. I also tried to invalidate cache to clean things up with no success. I have noticed that when I restart the program, the rename short cut in the Refactor menu item is active for a shourt while and then seems to disable itself.
UPDATE. Looks like I have to have the file closed before I can rename it. I don't remember having to do that in the past but maybe I just missed it.
Thanks for your help.
