Closing a note no longer posts it

Hello, i use Acrobat as a proofreader and use the "Add note to text" function a lot. Recently it seems to have changed - i used to be able to write a note and then simply close it, and it would be posted. Now i need to click Post (or ctrl return) to post it, and then close it. A small change i know, but i am so used to just closing the note that i keep forgetting to click Post, and keep losing sometimes quite long notes. Is it possible for me to change it back to how it used to be? Many many thanks for any help!
