I'm pretty sure that's a bug with the OS X version of GLUT. I bet
it gives 2 events for each key or button press. Probably a key up
and a key down event. I'll have to filter out the extra ones.

Hmmm, a quick calculation says 1024x768 times 32 bits per pixel for
the front buffer, 32 bpp back buffer, 32bpp depth/stencil buffer
adds up to 9 MB so that's out of the question with only 8 on board.
But you should have plenty of memory for slightly lesser modes,
unless the memory is partitioned badly. Maybe it abandons the stencil
buffer at higher resolutions to conserve memory? (That would explain
the problem since I use the stencil buffer to highlight the parts.)
Does ldglite print something different for GL_STENCIL_BITS and
GL_DEPTH_BITS when you go over 750x550?
Do you have any way to try a 16bpp mode?
Meanwhile what happens to the highlights? Do they change at all when
you select a different piece. I had a problem like this with the
Nvidia TNT that I worked around by using the ktx_buffer_region
extension. You don't have that extension, but perhaps I could use
a similar technique.
