2 problems I've run into trying to port this program of mine to windows
98:

(1) glPointSize does not seem to be working for windows. This isn't a
huge deal, but it makes life a whole lot easier. Since pointSize is
supposed to be supported by every OpenGL version, any ideas on why it
isn't working?

(2) i've set my mouse up to do point picking in world space, but for
some reason the mouse coordinates I'm getting from GLUT, inverted, seem
to be shifted down an amount specified by the taskbar. First, why is
this happening? As far as I know the taskbar is independent of window
coordinates, ie (0,0) starts at the lower left coordinates of the
drawing space, and goes to the edge of the drawing space. Second, how
can I get the height of the bar so that I can shift my mouse coordinates

up? Note I'm using GLUT so I don't have a window handle.

Thanks,
Fern
