I installed Networx on three computers. It works fine on XP and Windows 8. However, on my Windows 7 system, I had a problem. After running for a short time, about one hour, my PC stopped working and I needed to pull the plug to reboot. After the reboot, my PC hung again after about one hour. I uninstalled Networx and my PC runs fine. Any suggestions as to what I can look at to resolve this issue. This PC has very heavy LAN traffic, but very minimal network traffic.
