Not screwy at all, when you think about it.  MultiFinder has to play a number
of games behind-the-scenes in order to work as well as it does.  One of
these is to look at the number of files that can be opened at once listed
in the boot blocks and, when MultiFinder is running, increase that number
by some factor so that people don't run into unexpected problems that they
themselves cannot correct and don't understand (I can just imagine trying
to explain "boot blocks" to my mom, who just recently managed to use
MacPaint for a drawing of hers [yea mom!!]).

What sort of error message did you get using which version of ResEdit under
which version of the OS when this happened?
