These are actually the reasons why I said Xgobi is not very practical to use
under Windows. I should have pointed out my concerns about speed and the
need for special hardware and/or software. At this time I have a lowly Intel
P166 and if I use Xgobi and a software based XServer it behave just like a
486 40~66 mhz. You may call this practical if that's your pleasure. But for
those of us with low end PC's it becomes a big bit to slow for our pleasure.

Beside that I don't have any grudge whatsoever against Xgobi per say.
