Why not use _SFPPutFile?  It allows you to specify a modal dialog filter
procedure to call after doing the standard filtering.  In this procedure,
you simply watch for update events, and re-draw the highlighting when
an update comes thru.  (Be sure to double-check the grafport in the event
record!)

Is it possible to use TestException() (SANE reference manual, pg. 54) to
check for INEXACT after a conversion using Str2Dec()?  I haven't done
anything yet with exceptions, so I am kind of interested in this one too.
