Comment 1 for bug 917037

The error message for alerting the user to another instance of Plover running should be improved and I like your suggested wording. As you suggested, examining the process list might work as well, though it leaves room for ambiguity and false positives. Something like:

ps -U $USER -u $USER u | grep `which python` | grep plover

might work on *nix systems, but I don't know what the equivalent would be for the experimental Windows port of Plover.

As for the explicit exit button, I'd rather rely on the window manager to supply its own window close button, which should be properly handled by Plover. As you mentioned, nearly all window managers provide such a button.

Thanks for all the suggestions. Plover has a lot of rough edges and it's exactly bug reports like this that will help smooth them out.
