Object Graphics [message #39394]

I started playing around with Object Graphics today. I've used Java
objects in IDL plenty of times, but never IDL's own objects. Anyway,
the first thing I tried to do was create an IDLgrWindow, however IDL said:

IDL> window = obj_new('IDLgrWindow')
% OBJ_NEW: Creation of backing store pixmap failed.
Requesting backing store from the server.

What does this error mean? For what it's worth, this is on Linux,
specifically Fedora Core 1.

Secondly, is there something, anything out there which actually explains
what's going on inside the object graphics system? Or at least does
better than RSI's documentation? I've worked with graphics systems
before, but never with something quite like this. It took a good 30
minutes to figure out how to draw a single diagonal line. Oh, well.
