[Bf-docboard] Blender screen captures on Mac OS X

[Mike Wirth]

I'd like to do some screen captures from Blender 2.32 to accompany 
documentation suggestions I'd like to make.  However, the normal 
built-in screen capture on Mac OS X 10.3.3 generate a blank image. 
Any suggestions?  Is there another utility, or a feature built-in to 
Blender that will allow me to generate images (png?) of arbitrary 
Blender screens (including button panels, object browsers, etc.)?

TIA,

Mike
