This happens for two reasons:

	1. Some sounds have garbage in their header fields; prior to
	   System 6.0.7, these fields were ignored.

	2. The 6.0.7 Sound Manager is broken in a number of ways, and
	   the lack of sanity-checking code is just one of them.

There are a few ways to solve it:

	1. Use ResEdit to zero out the offending fields.

	2. Use Sound Mover to copy the sounds to a new file.  You can
	   just copy all the sounds from one suitcase to a new
	   suitcase -- you don't have to choose only the offending
	   sounds.

	3. Go back to System 6.0.5  [my personal favorite].   :-)

The second way is obviously the easiest, and it seems to be
fool-proof.

Interestingly, Sound Mover seems to contain just the sanity-checking
code that Apple failed to include in the Sound Manager, since it will
play the questionable sounds without problem.  It's an all-around nice
utility, and it should be available on America Online, CompuServe, etc.

Also, Hypercard 1.2.5 will work under 6.0.7 -- at least until it has
to make a sound.  Just type "beep" into the message box and viola!
Your Mac crashes.  Let's hear it for backward compatibility, eh?
