I don't know about everything, but I know what MS did to Skype. In July I started taking a language course by Skype on my MacBookPro. Not only would it stop working approximately hourly, but it then refused to Quit. Force-Quit was necessary to get back to where Skype could be restarted.
Every couple years the company updates to a newer version of MS OFFICE and I have to make changes to my spreadsheets because the new version does something weird to my spreadsheet.
Every time they announce that a MS update is going to be pushed I get nervous.
Other people use my spreadsheets on backshifts so I figure I might be getting a call in the middle of the night.
[[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.
