It has come to my attention that the latest version of Measure Numbers
crashes Finale if you press the Set Font button. For various reasons,
including that it may be a bug in Finale, no quick fix is likely to be
forthcoming.

As a workaround you should use the version of Measure Numbers included
in the link marked "for Finale 2004 running under OS9". This version
works with all later versions of MacFin and also works natively in OSX.
However, it does not exhibit the problem.

Answer on-list if you would like a more technical explanation of the
problem.

Thanks.
