Horizontal thickness is 6 pixels, vertical 3 pixels. >> height is variable. > 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? Ah ok. I was looking at the DisplayAlert() code, where the height is a variable parameter. The exec Alert() function (which calls DisplayAlert() internally) uses a height of 40 pixels. >> Flash timing is 64 frames on, 64 frames off. > 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? The frame timing relies on the vertical blank counter by using graphics.library/WaitTOF(). This means that the blinking speed is different on a PAL or NTSC machine. Alerts are displayed on a default PAL (or NTSC) 2-colour hires screen mode.
