Long story short:
Skype video wasn’t connecting, internet suggested it needed a revised launch Command that specified 30ms.
I replaced what was there with what I could see in the screenshot, and broke it. obviously there was more in the Command field that was displayed.
I uninstalled Skype via Yast, and reinstalled, hoping it would replace the Command i’d put in KDE Menu Editor. It did not.
So, I need the full text string for what needs to go back in the Command to get Skype working again…
… preferably with whatever addition is required to stop skype video crapping out.
