No.  The 32-bit program runs in 32-bit mode, I believe.  If it does
most of its work in 32-bit mode, with say only 10% of its work making
calls (through thunking) to 16-bit code, you will see a significant 
performance gain.

If however, the program is very simple and mostly uses calls into
16-bit libraries, you will see a performance loss.  It depends on
the program.

How complex is Mosiac?  I don't know.

Yes and no.  Yes, if memory is the concern.  Yes, if the program
is mostly calls into 16-bit code.

However, no if the extra memory isn't a problem and if the program
does a lot of its own work.

Also, 32-bit code is beneficial to NT/Chicago beta users.  But this
is not the normal Windows user.

Sincerely,
Brian
