Installed latest update, and after that, if PingPlotter is opened (not even running pings or any activity yet), I can no longer reach anything. DNS resolves, but any pings, URL loads, email, etc, fail on my laptop with expired in transit messages. route table not changed. Not sure what PingPlotter is doing here, but shutting down PingPlotter returns laptop to normal. I tried a reboot to test, and same problem after rebooting.
