Sympatico was no help. They said it was not a Netscape or a Sympatico problem, but a Windows problem. They gave me the support number to call Microsoft, but there would be a fee. I tried searching the knowledge base, but got nowhere.
Today, I tried again to play with it. I moved the wallpaper to one side (which you're not supposed to do if things are right) and instead of clicking on the globe, I clicked on the blank screen. A different menu came up, and on it Network Neighbourhood was ticked. I clicked on that and the tick went away, and so did the extra window under the desktop.
Such a little thing and no one could figure it out, including a chap in New Zealand who is a whiz with things.
I'm so darn pleased.
I wanted to let you know incase you ever come across this weird little problem.
