I’ve just upgraded to High Sierra and WriteRoom 3.2.1 no longer scrolls all the way to the bottom of most documents. These documents are .txt files all smaller than 30KB. WriteRoom shows the first few screenfuls, but won’t render anything below that. Sometimes it shows only the top of each letter on the bottom line.
I have verified that the full contents of the files are still on disc.
This is making WriteRoom unusable for the documents I need to work on.
