Hi all, just a quick question is it a bug or is it somethign wrong with my system.

I have dual Monitor setup and 2 zoom docks runing on one monitor and other on the second one. The problem I am experiencing is that my zoom dock on my secondary monitor will not stay after 'fast user switch' in Vista, however it stays ok if I reboot, but each time I switch to another user and come back my dock gets back on top of other dock on the primary monitor?
