I have had a copy of Juggler running under Finder 6.0b3/System 4.1 for a
couple of days now.  It is nothing short of fantastic: at least it will
be when all the discrepancies between it and some applications have been
sorted out.  I have been running applications created by Microsoft FORTRAN
v2.2 with QUED/M and the fortran compiler on a 2Mbyte Mac// with Juggler.  I 
find that I am dropped into Macsbug (v5.3 for 2Mbyte Mac// from CIS) when
the application finishes.  This occurs both with McFace.sub and with the
dumb terminal window.  I can run the same application under F5.5/S4.1, which
came with the Mac//, and I get an error 64 (drive not installed) which is
displayed by the error handling routines installed in the application.
The exit to Finder is then smoothly executed.  But when I am dumped into
Macsbug 5.3 from Finder6.0b3, I cannot exit to shell and must reboot.
Can anyone suggest an alternative context switching environment to use
until the Juggler is officially released without the gremlins?
Many thanks.
