Strange thing is, I don't get any error pop up windows (using either W7, W10, or Windows Server 2019).
If I click on the taskbar server icon, it does not respond (I guess because it's stalled/errored).
If I use the X to close, there are "ghost" icons left in the taskbar, eg:- the main Ripbot icon, and a couple of server icons.
And yes, the only option is to "kill it" (Ripbot.exe, and whatever instances of Encoding Server that are showing), with Processhacker/task manager.
And btw, when I went to start the job queue, today (that I set up yesterday), without adding a thing, it would not start encoding the job's, UNTIL I aborted, and backed out of Ripbot, and restarted it, then it was fine....
