Font Size Won't Change: Prepare Forms

I am having the identical problem. I change fonts for form text fields daily on forms from clients and suddenly today on one it just defaults back to Helvetica 8.5. This happens whether I am editing an existing Text Field or create my own with different properties. In the end, they all say Helvetica 8.5. I checked the Fonts tab in the doc properties and tried ones other than Helvetica and they don't work. The "encoding" for Helvetica says "Custom" and I don't really know what that means. 

I ran into the same problem. When I edited the Text Field Properties and unchecked Allow Rich Text Formatting, I was able to set the font size.

This is all wrong, form pages should be a normal page size, not 45 inches. But if you want it that size you will need either

- to zoom to 100% to fill the form (where you will see the fields as normal size), or

- define very large form fields (perhaps 100 point or more).

What is the zoom percentage and original size in inches of the document? The size in inches (or mm) can be seen by hovering the mouse in the lower left corner.
