Hmm. I'm curious how it works on your machine. There's not a problem with my
LDraw directory or $LDRAWDIR definition; it's an environment variable,
regardless of where it's defined.
The problem isn't with the LDraw parts, its with the visible interface. It feels
like maybe a GLUT problem - just the last step to the screen that's flaky. The
screen is blank, and gets re-blanked whenever you try to rotate the display.
Displaying a menu will paint whatever is underneath it, but it doesn't get
repainted until obscured again. Screenshot with a model loaded:

Showing the contextual menu reveals the background color behind it, but no
model, so I'm not really sure where the problem lies. If you open the little
settings panel, it remains visible after you close it - it's no longer
"clickable," but just its image that hasn't been cleared.
Anyway, this is with ldglite 1.0.18 on OS X 10.4.8. It'd be great if there's a
ready fix.
