Fixed!
I solved the problem.
NVIDIA was drawing the icon
onto the screen.
Previously, with the old Quadro
card we were not using QUADBUFFERING.
For some reason it was not supported.
With the new one it is, but we were
still using the old 'non-quadbuffered'
way, which resulted in the icon being
drawn to the screen but with
3D still activated.
I switched back to QUADBUFFERING
and the icon went away with the
viewport being still in 3D.
Hopefully, now if anyone has that
problem they'll see a solution.
Thanks,
George
