Did you get my last post about how all of the keys that do anything also
casue LDGLite to step the model? From now on, should I say LDGLEdit for
edit mode? Should I say LDGLDraw (a bit redundant) or LDGLIte for the
viewing mode?

For 750x550
GL_VENDOR ='ATI Technologies Inc.'
GL_RENDERER ='Rage 128 OpenGL Engine'
GL_RGBA_BITS: (8, 8, 8, 8)
GL_DEPTH_BITS = 24
GL_STENCIL_BITS = 8
Buffer Swap Mode = 0
Editing mode = 1{0}
at 800x600
GL_VENDOR ='ATI Technologies Inc.'
GL_RENDERER ='Rage 128 OpenGL Engine'
GL_RGBA_BITS: (8, 8, 8, 8)
GL_DEPTH_BITS = 24
GL_STENCIL_BITS = 8
Buffer Swap Mode = 0
Editing mode = 1{0}

I just tried that. I tried it while LDGLite was running, and the colors
went all to hell, but the highlighting function started working
correctly. When I set my screen to 16bit (1024x768 pixels) before
launching LDGLedit, everything worked fine! I could even run LDGLedit at
1024x768! (Woo hoo)
Also, I noticed that turning down my screen resolution to 800x600
(leaving the depth at 32 bit per pixel), the part highlighting works
properly.

No, they don't change. They look the same.

I was just about to start looking at the other thread, but it is late
(2:00 am late), and I need to go to bed. I look into the mouse
rotation/debuggin mode stuff tomorrow.
Thanks!
Goodnight,

Do you see these anomalies in OS X too?
