;
; More fur for the beast: I've long known there was a bug in the Alert()
; function. Recently on the net someone implied that it was different on
; their machine. Strange says I, and whipped out the assember:
;
; Simply put, on machines with $C00000 memory, recoverable Alert()s
; simply are not recoverable. I have not tried non-$C00000 memory
; as I have none to try.
;
; This means that on all A2000s, most A500s and many A1000s recoverable
; alerts crash the machine. Remove the $C00000 memory and the problem
; goes away.
;
; Alerts do a system sanity check, and exhibit the same behaviour if
; some naughty program does not use SetFunction() when patching library
; vectors, for example. Something gets screwed in $C00000 and that is
; preventing alerts.
;
; Oh, well, Alerts are almost as broken as Intuition string gadgets even
; without this wrinkle.
