[[but it then refused to Quit.]]
There is a desktop shortcut you can create to force it to quit- the following are instructions from somewhere- can’t remember where i got them- but it works-
-——————————————Close Skype Completely Version 1————————————
A. Right-click on any blank portion on your desktop, then select New >> New Shortcut
B. In the Location, go to browse, then locate “C:\Program Files (x86)\Skype\Phone\Skype.exe” - click ok,
then put a space at end and then /shutdown so it will look like “C:\Program Files (x86)\Skype\Phone\Skype.exe” /shutdown (make sure quotes ARE in there)
C. Enter Skype Shutdown as the name of the Shortcut, click Finish.
D. You can simply click that shortcut whenever you want to quit Skype (right-click on the shortcut icon then select Properties), or even assign a hotkey. For example, you can set Control + Alt + 1 as hotkey to easily quit Skype.
Macs do not have "C" drives.
Macs do not have .exe files.
And a whole bunch of other things...
