F7 Spell Check Does nothing

thank you for assisting in any event.

Update:  Completed online help discussion.  Person indicated, with Patch9 it simply highlights with red underline. Yes this does occur. 

However, I recall RH classic had a dialog that took you through all the pages.  Simply indicating failed spell on a project with 100's of pages is pointless. I was directed to submit a request, which I did.  Not sure why I have to request a feature that I had previously.  But I did.

Even if I've got it selected in the Preferences, I'm finding it works sometimes & sometimes not - I was taking existing words and adding deliberate errors to them and I found I have to highlight the word, then go to Edit > Spell Check to get it recognize the error. 

Looks like it's working here. Is spell checking enabled in preferences?
