I'll have to disagree with this. It takes me far longer, far longer,
to develop an application in IDL than it would in straight C++ and
OpenGL. A good C++ compiler catches a lot of errors that IDL's
"compiler" doesn't. Many of these errors, such as undefined
variables, only show up at runtime. In a complex application it takes
forever to validate the code again after a fairly minor change. If
performance is a concern at all. Don't use IDL. It's not exactly
speedy.

Also, IDLDE's constant crashing doesn't help the development process.

Ahh.. I would buy the best video adapter you can that will run with
IDL. I have one of the best adapters available, it's an nVidia by the
way, and the driver crashes under IDL. Just with IDL, it doesn't seem
to crash with any of the the other apps I've tried. I'm forced to run
in software mode now. Make sure you can exchange the graphics card if
it's not compatible with IDL.
