   What's faster, using CopyMask, or CopyBitsing with a maskRgn
parameter?  I'm talking about transfering a 200 by 200 pixel bit map
from offscreen to onscreen.  Does anyone know?
   Also, no one has responded to my last posting about a problem with
the Sound Manager in System 6.0.2.  Does anyone (preferably from Apple)
know if there's a limitation in the Mac Plus that prevents it from 
playing asynchronous sounds in rapid succession?  My program seems to
get mangled and land on an odd word boundary when I dispose the sound
channel after playing a lot of asynchronous sounds on the Plus, but the
program works fine on a Mac II (probably because of the 68020).  A
response would be much appreciated!  Thanks!
