I had a file that was read-only that I wanted to edit, so I went to explorer and turned off its read-only flag. Then I switched back to Aurora, but Aurora still wouldn't let me edit the file (typing had no effect, ie the same behaviour as with a genuinely read-only file).
So I edited the file in another editor, saved it and toggled back to IDEA. The 'lock' icon had disappeared from the filename tab, however I was still unable to edit the file. A
was thrown (see attached log).
This is 100% repeatable. WinXP.
