Can't Adjust Font Size
Occassionally, the font size editor in the text box gets stuck and can't be changed. This is typically caused by formatted text being pasted into the text box (from a web page, Microsoft Word etc.)
The fix is simple:
* Highlight the text in the box
* Double-click on the word "Size"
* Type in a font size (any will do).
This will reset the editor and allow you to adjust.
Here's a short video that illustrates the fix:https://youtu.be/AQagKxAhR6E
