With Bonjour running, Windows 7 won't wake from sleep?

Have a problem of when put Windows 7 to sleep - it won't wake - have to restart

Went thru the "clean start" process - eliminating services that might be causing the problem

That process showed it was Bonjour - with Bonjour running, doesn't wake from sleep; with Bonjour disabled, problem disappears

Is there anything that can be done to allow Bonjour to run without causing the sleep/wake problem?
