Not much to say here. F7 or Edit>Spell Check does absolutely NOTHING.
Looks like it's working here. Is spell checking enabled in preferences?
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.
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.
thank you for assisting in any event.
