Yes.

Not that I know of. I didn't change the GTScroller command at all (well, I
hope not).

No, it is not possible. I just checked the gadtools autodocs, and the top,
total and visible are all used as WORD's, so it is the gadtools.library
which is limiting you to the range -32768 to +32767 (or maybe even only 0
to +32767??).

I don't know. It doesn't seem to want to work by showing only 1 visible at
each time. I'll write another test program in C and make sure it is not
some problem with Blitz - I do not see why there should be any restriction
like that.
