What's the deal with graphical debugging under FSDB? The faq said,
under 'graphics debugging', somethign along the lines of "Of course,
you can just use fsdb". But if I try to step past a switch to graphics
mode, everything goes blank; FSDB is running, coz I can Alt-X out and
type MODE CO80. Have I misread, seen a mistake in the FAQ (it's not
the really new version, I haven't had time to DL it yet), or just not
enabled something???


Thanx,
