Thanks for your reply.
Yes, I change the text, then click File, then Exit and the words “Enter Text” still appear in the middle of the title window in addition the to text I added.
I think there is something strange happening on my computer. Those same words “Enter Text” appear in every title regardless if I use NewBlue Titler Pro, ProType Titler, Titles&Text, or (Legacy) Text.
I don’t know what to try next.
