The my places solution sounds good. I suspected the autodialing might be caused by my second, networked PC. Since I posted this problem a week ago, the problem is less frequent but still dials, at times like it has a mind of it's own.
I tried the above fix - My Network Places. But I am unable to follow your instructions. I have home XP - if that might make a difference. When I select Properties, I have no "advance tab". I have two tabs - General and shortcut. Both have Advance buttons but neither of these has any options about dialing.
Any thoughts? Thanks again. Ron
