[OpenSCAD] Keyword 'color' not working in Windows OpenSCAD?

[Nick Pelling]

Hi everyone,

I'm just getting started with OpenSCAD running under Windows, but I 
can't seem to get any color to display (apart from the default 
yellow), nor indeed alpha. I've tried color("red"), color("Red"), 
color([1,0,0]), etc but nothing seems to make any difference. I'm 
using a Nvidia GeForce 8600 GT, might that be the problem?

Everything else seems to work fine. :-)

Thanks, ....Nick....

PS: are there any cross product and magnitude functions? Thanks!
