If I recall correctly, the weird 1x1 window had something to do with 
getting the layout to work.  I think if a panel only had one child, it 
wanted to resize the child to be the full size of the panel which I 
didn't want.

Ah!  It's entirely possible that I patched my copy of wxgl for just 
this problem and didn't get that change into the source tree I 
distributed.  I'll look into that.  I last worked on this almost 
exactly a year ago so I don't remember the details very well, 
especially since I was trying to get a installer release out in a 
hurry.  I'm pretty sure this was also before we had migrated to bzr 
and created our own crystalspace fork, so change tracking was a bit 
more difficult...

Isn't cross platform development fun?
