Re: Why is "Return to Last Menu" greyed out for the Title button?

I do not claim to understand this.  See Title Button and Menu Remote here:

You will see that, in Encore at least, the Title button is set for the whole disk, and the Menu Remote is set per timeline. It looks like you can do what you want by selecting one or more timelines, and setting the Menu Remote to last menu. but the user has to select the menu button, not the title button.
