Ken,
While my server runs on unix, I do the development under Windows, where the
work around is unfortunately no good. However, as the code has grown I
actually appreciate some other features of object graphics, such as alpha
blending which I use frequently. While alpha blending is only a simple line
of code, the keyword solution is pretty slick.
