Cylindrical map projection screwed up? [message #13526]

I've been doing some stuff using cylindrical map
projections using set_map. So, darn it, I expect
my lines of longitude to be vertical, and my lines
of latitude to be horizontal in the image.

But, when I set the LIMIT keyword to just look
at a small portion of the globe, this is not
the case. In fact, I only get a true cylidrical
projection if the min and max latitude have the
same magnitude, ie. -30 to 30 degrees.

Is this a bug? or am I missing something obvious.

I'm running IDL 5.1 on hp-ux 10.20
