Uncheck option, hit apply or ok.
Return to option and it is checked again.
With network drives (via automount + cifs) this causes medit to lockup on startup when network is not connected.
The solution being to kill medit, delete the autofs, kill cifs, restart autofs, restart medit, then close the inaccessible file from medit before re-enabling autofs.
Alternate solution to manually delete the medit.sessions file before starting medit.
Ideally the editor would never lock up at all.
When medit is started up with a file which is accessible, it is annoying that medit locks up because it automatically tries to open files which are not accessible.
I'm thinking of replacing the medit binary with a shell script which deletes the session file in order to correct for this bug.
