This is a long standing complaint. The only bright spot is that in F26, you can not only drag the window larger, you can enlarge the contents of the frames. I'm really surprised that they haven't done that with all of them. I haven't even looked at F27.

I don't know what you mean by "smaller than the Pharma font." If you have (forgive me) "normal" vision, you shouldn't need a magnifying glass. What size is your computer screen? Also, most (all?) computers have accessibility viewing options. Have you explored them?

First, pharma-font is the very small font used on Rx sheets you get with your Rx.  All 15,000 works on a sheet of paper that is 4x17.  In my case when, for example in expression selection, you create a new expression, the font size you choose is not representative in the selection dialog boxes--its like 2pt in size.  My screen resolution is the default for my MacBook Pro.  This is the only software package I have that behaves this way.  My Adobe CC behaves perfectly fine and so does the Microsoft Office 365.  

I just don't understand how Finale can continue to go on and not correct something so basic as the display on the screen.  You can't enlarge the display of the lyrics, for example, unless you enlarge the score via mac command + .  This is basic UX design that has failed miserably.  

Again, this is a serious violation of ADA, IMHO.   I really do need to learn Dorico. LOL  It doesn't have this issue at all.
