That's interesting. When you asked me to check for node.exe on my system I did see that it was a part of Visual Studio as well as the Adobe products but it didn't seem important. I wonder, is it possible your system has been downloading data like updates from Microsoft? I know I have been receiving multi GB updates over the last couple of weeks. Usually though you will get a message that a system restart is necessary-probably not connected but food for thought.
Another update on my problem.
I have finally been able to get high speed DSL at my house. Bell upgraded their equipment at the local switching station and I was at their office to sign up before they even got the last wires hooked up. I've been dreaming about this ever since I moved into this house in 2000.
I now have unlimited data so I turned node back on again. I still don't know what it does or why I have 3 versions of it installed but just in case it does something important I guess I'll just let it run.
Terry, you though it might have something to do with Windows Updates but on the days I was getting the 3 to 400 Mb downloads no updates where installed for Windows. Even when node was turned "Off" I was still getting regular Windows updates.
I hate unsolved mysteries but I think I'll just let this one go rather than driving myself to where I need a system update for my brain.
Thanks again Terry for your help,
John
