When editing the font size using the Font Toolbar (not the properties toolbar that shows up when editing text), if I single click the font to edit the size, then use my keyboard to enter a double digit number, the font size will automatically enter only the first digit.
For example, if I want to change the font from 12 to 32 using the Font Toolbar, I click the font size box, begin typing "32", but the box immediately enters "3" for the size. Then I have to click the font size box again, un-select the number, and click to the right of the number to enter the the "2".
I have V21.7, but it's been an issue with past versions as well.
