I've been agonizing over this skin cut for years...and now it's in the O365 version as well.
Open a testing page, set cursor at least one line feed from the title field
Set the default font to Tahoma 12 Black, type some characters and press <Enter>
The next line resets the "default font" from the one I want to use and uses the Microsoft default font for every productivity app: Calibri at 11pt, Grey so the elder computer users can't see very well.
Sp, why were we so happy with Win3.1 because we got True Type fonts and families? So we can't set a page to a single font, size and character color?
