When using Ctrl - + to change font size it now globally changes fonts in all emails. I believe it used to only affect the font size in the email you were viewing.
Anyway to have it not be a global setting and affect only the email being viewed?
It was always a global setting.
Where it may not apply globally is if you have two message open in separate windows, then you change the zoom setting in one. If you close that window, the settings for the other window will be used globally.
Thank you Gary for the clarification.
