And what is the thickness of the frame?

Um.. no? I mean AFAIR DisplayAlert() can display various messages, leading to variable height of the box but the exec messages had (have) fixed layout leading to a fixed height, didn't they? What was that one?

64 frames... meaning different speeds for PAL and NTSC timings? And - BTW - how does it distinguish which mode/screen timing it should use to display the "deferred" Guru. I remember I never had timing problems with my Amigas displaying Guru, meaning they most probably used something closer to PAL than NTSC. But the hardware and the ROM was the same in the US, weren't they?

I take the data above comes from those :-)
