"You must restart your computer to apply these changes" on each dock/undock

[orgwizard]

sorry for the delay, I how hopeing to find a pattern or something that allowed me to reproduce the restart prompt more reliably.
unfortuntely, it's still happening, several times now, though not after every shutdown and start up, and turning the dock on after login.

so there must be some other factor in play that I've not yet figured out.
