Hello Netters, 

I have a few 32 Bit quickdraw questions and hope someone can give me some 
suggestions to follow. We are developing on a MacII with 2 displays 
(one 32 bit, one CLUT), using MPW 3.0 and SADE. 

1) How do you create and draw into a 32-bit color window on a direct device?

   We are using 2 devices, a CLUT and a direct device.  So far, we have been
   unable to create and draw into a window with the direct device 
   characteristics (32 bit pixel size).

2) How do you access the pixel map information associated with the window on 
   a direct device. In particular, when we try to access the memory 
   associated with the pixel map, we get an ## address out of range ## 
   error in the SADE debugger.

3) Finally, does anyone have any guidelines as to when it is necessary to use
   SetOrigin? (oops, nothing to do with color quickdraw here, folks)

Thanks, any replies would be appreciated.  What are you all doing with 32 BQD?
