Does anyone know why my window closes when idle for just a minute and I loose my network connection? It happens to an application and a document window. The computer does not lock up but I have to restart to get my network connection back. As long as I keep working it stays connected but if I stop to answer the phone then the window closes. I'm using Windows XP Pro. I replaced the network card in the computer and it seemed to speed up the response time but then as soon as I stopped, it closed my window in about 1 minute.
Any suggestions would be appreciated.
