Actually, I  think there's a better workaround (no immediate code  
changes). Check the multicast entry in your ~/.AccessGrid3/Config/ 
preferences file. It will probably be set to False if you're setup to  
use a bridge by default. Change this to a 0 (zero). Similarly, change  
it to a 1 if it was set to True.
