I made a program that puts up a window containing a few Forms,
a Matrix and a Button.  It works fine except that when the user clicks
a on the window (a variable number of times, 1 ~ 3), the program fails
with the following error:

		  'Assertion failed: Unlocking Focus on wrong View'
				'Bus error'       (sometimes 'DBus error')

In case it helps, the program is recording sound continuously into two
buffers
from the microphone.  Each time a buffer is full the Forms and Matrix 
are updated within a completion routine specified by SNDStartRecording().  
The same routine then calls SNDStartRecording() on the second buffer.  This
call is made *after* the first buffer has been processed and the views
updated, so there should't be two completion routines running at the same
time.  

The NeXT is running 2.1, and the program was written using IB.

I have little experience with the NeXT, so if anyone has an idea as to 
what might be wrong, or how I should find out, I'd be grateful.
