As you saw, the screenshot is from the Mini-Client. After that I switched to Chrome. The error still occurred there. I had to repeat clicking on the *on, to occasionally get into a fight, between those I only got the same floating message about system error.
As for the requested file, when I typed "hylogfile" in, it brought up the "Save As" window to save "log(2016-11-0723)." Wherever I tried saving it though, no file was created. It may not work in Chrome, and I assume it will be useless if I quit then start the Mini-Client for saving it.
