I'm not sure why this would have started happening as I was using the same OS (Win 7) and the same version of PP Pro for some time. Anyhow, I can start a ping to a host, go off and do something else and when I come back I find it's stopped and I have the option to Resume. Sometimes the ping will run for several minutes, other times for only ONE ping. I upgraded to latest 3.30.3p but the problem persists.

If I have multiple pings going, they all stop at the same time.

What can I do to troubleshoot this further?

Thanks
