When I minimize the current krpano testing server on win10, it runs OK until I try to restore it, when it crashes. The form of the crash depends on whether it is minimized to the icons tray or to the start bar: from tray, I get windows error box "krpano testing server has stopped working" then "searching for a solution". From start bar, I get the properties window of the desktop shortcut from which I launched the server, with no notice that the server itself has stopped.
This is not a showstopper, but I hope you will be able to fix it.
