SpamSieve 3 won't quit

I just upgraded and purchased Spamseive 3.0
On shutting down, spamseive stops shut down. Quit is greyed out
I did see there is a new rule: Rescue Good Messages SpamSieve
Mail did quit but SpamSeive wouldn’t

Please send in a sample report so that we can see why SpamSieve isn’t quitting. If necessary, you can Force Quit it from the Apple menu.

Rescue Good Messages SpamSieve is not a new rule with SpamSieve 3. It’s something that you would have created yourself using these instructions.
