Summary: A2000 Guruing.


Having had my A2000 (B2000, really, even though the box was labeled in
German), I would appreciate some help with a particular problem.
I have a code that neglects to clear register D0 before it does a
_LVOOpenLibrary.  The garbage in D0 is larger than 33 so the library
fails to open;  so, since we are trying to open dos.library, there is
no way to report this failure other than through Alert.  However,
when the Guru is summoned, with a recoverable alert, the entire screen turns
blue and the power LED begins to blink benignly.  After waiting a while,
I administer the nerve pinch and lo, the requstor appears.  I press the
right mouse button and the machine resets itself.  When this code ran on
my 1000, it properly displayed the alert and proceeded to clean up and exit
properly when you pressed the mouse button.  No more.  What is the source of 
this problem?  Any speculation is welcome.
(oh, one other thing, I meant to say that I pressed the left mouse button
in response to the alert; my mind wanders.)

Thanks,
