Remote Assistance Not Starting

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

I'm trying to use MSN Messenger to start Remote Assistance with somebody
else, and when they send an invite, I choose Accept, but then nothing
happens. My screen says I have accepted the invite, but his screen still
shows nothing has happened (it doesn't even confirm the invite was accepted).
Am I missing something? The help files say to ""Take Control" on the Remote
Assistance Window, but where and what is the Remote Assistance Window?

Thanks
