For the past several months I've been programming with LS C, with
liberal use of MacsBug.  Many of my system bombs are easily recovered
from by using ES (Exit-To-Shell) or EA (Exit-To-Application).  Many of
them are totally beyond recovery. Occasionally, I will exit from
Macsbug and everything will run fine -- except that the mouse and
keyboard have become disconnected.  Is there a trap I can execute from
Macsbug that will reinitialize the Desktop Bus, so that I don't have
to reboot?

(2)

If I take the time to select "Shut Down" from the Finder, the next
time I boot my hard disk (an internal HD20SC - in my Mac SE with1 MB
RAM) it takes maybe a second to display the "Welcome to Macintosh"
dialog.  If I don't select Shut Down, the drive is active for more
than a minute - I've got a very full hard disk - before it continues.
I'd like to know, first of all, what the HD thinks it's doing during
this interminable pause; second, exactly what "Shut Down" does (I've
seen DAs that park the heads on a SCSI drive, so I presume that Shut
Down does not park); third, if there's anything I can do to fix it --
if there's no general fix, maybe there's some way I can access the
Shut Down code from Macsbug after an unrecoverable crash... (I can
hear you all thinking, "Fat chance..!")

Is there any way to get SelectDialog to return me the part code of the
control that was just pressed in a modeless dialog?  I've got a dialog
with scroll bars whose elevators work fine, but the arrows and grey
area remain blind to the world...  I caught the tail end of the Dialog
discussion on this board, so I presume that Dialogs don't like
Controls very much.  It doesn't hurt to ask, though -- right?

Thanks in advance,
