When I select "Ping (get report)" on a station in the last heard beacon window, it executes as expected then disconnects and immediately executes again. I don't know if I have something configured incorrectly or initiating the ping incorrectly. I single left click the desired station to highlight it then right click to get the drop down list then left click the Ping (get report) item in the list.
To see this working, head to your live site.
It happened when using the right-click menu, however it seems to be working normally for the last week. I currently have version 3.6.6 and have not had it happen in this version.
I'm using version 3.5. It does not happen every time.
Thank you for reporting. What version of VarAC are you using ?
