[DUG] OpenGL drivers and GLScene

[Phil Middlemiss]

Found it - as you suggested, a version check that doesn't look past 
version 1.x is at fault. We haven't been updating the GLScene version we 
use for a while (if it ain't broke....) and now OpenGL have version 2 
out, which I guess the people in question are using. A fudge will have 
to do for now while we look at the latest GLScene offering.

Cheers,
Phil.
