That could well do it. It's the result of a somewhat odd (in my opinion)
decision by Microsoft: in Win95, there was a switch to having BMP
generation being done through the graphics card. (Previously, it had
been done through a separate device driver, which provided much
greater flexibility.) Some authors of device drivers carefully implement
this function. Others, it seems, don't. As best I can tell, if the
device driver for your video card isn't quite right in this regard, you're
essentially out of luck.

If you're using PaintShop Pro (or some similar graphics package),
you may have an assortment of screen capture tools, such as
"capture entire screen", "capture window", "capture user-specified
rectangle", and so on. PSP has a "capture client area" option that
will do what you probably want: grab the chart area, without including
the menu and toolbar area.

About right-clicking troubles: I'll keep all this in mind, and there are
at least a few fixes that may not be too problematic. (For example:
instead of having to click on the center of a nebula or open cluster,
it should be possible to click on the outline of such an object. After
all, you can _see_ the outline, whereas you have to guesstimate
where the center of the object is... not necessarily a problem when
you're zoomed out far enough, but an annoyance when you're
zoomed 'way in.)

Having a list of objects pop up when you click on a point would
usually be more annoying than helpful. Most of the time, you
can click on the desired object right away, and wouldn't want
to have to first click on it, then confirm that yes, that's what
I meant to click on. (Obviously, this is less likely to be true
if you've got a really crowded screen. In such a case, you may
want to consider dropping the limiting magnitude down a notch.)

But a moving indicator showing the object on which you would
be clicking could be very nice. It could mean you need only wave
your cursor over the object to immediately get a tooltip-like window
telling you what the object is, plus perhaps some very brief details
on that object. Unfortunately, I didn't rig up the program that way
in the first place. Retrofitting it to work in that manner wouldn't
involve rewriting Guide from scratch, but it would come close to
that. I may come up with some means of improving the "right-click
confusion" problem, but it almost certainly won't be through
either of these means. I'll have to come up with something that
will fit the existing scheme of things somewhat better.
