--It's the the "busiest" menu I've made yet, so I apparently wasn't seeing this in earlier projects, since the menus were simpler.
But there's no visual feedback while working in the editor to warn you when things are overlapping in a way that won't work. In my old Brand X program, the outline of text or image would suddenly have a bright red border when they were placed "illegally" in the menu. You could instantly see when you'd moved the offending item enough so that the program was happy.
--Without that feedback, I'm working in the dark - and I'm not getting it right yet. I don't know exactly what to look for. It seems like text can seem to overlap a bit and it's acceptable - but how much? This is an awful lot of work, going through 6 pages of chapter buttons, 4 chapters per page - and like I said, I don't seem to be fixing things yet.
That error message isn't clear either - "a menu thumbnail (menu caption")---I don't get that. Those are two different things, captions and thumbnails-.
Any tips?
