default zoom for new windows is 55%, cannot reset back to 100%
This problem just started happening recently, but my default window zoom is now 55%.
Changing the default zoom to 100% under Options. Appearance, User Interface Zoom has no affect on new or old windows and all windows zoom has to be changed by hand.
Any ideas on what is causing this problem and how to resolve it?
Mac OSX 10.12.3 and Vivaldi 1.8.770.54 (Stable channel) (64-bit).
I'd be happy to reset my configuration if that is what it takes to resolve the problem.
Thanks in advance.
