Hola!
Having an issue with both the AppStore version, and 1.5.5 - Beta 1 regarding TypeKit fonts. The fonts were synced to my computer, I attempted un-syncing and re-syncing without success. Essentially what happens is as follows.
TypeKit font selected from drop-down Default font applied normally Weight drop-down properly displays various weights Hovering over, or arrow keying across certain weights appears normal Some weights kill the drop-down display while still showing the preview in document Inability to select the font, in fact clicking the blank area is prone to crashing the program
Let me know if you need more information.
