Correct, this is a general problem with architectures that use scripts
to build the UI. As for "2 files", you'd only have one with an
architecture that supports binary resources (like HyperCard,
SuperCard, MetaCard, ToolBook, etc.) because the object description,
the data values (checkbox/radio button state, text in fields, etc.),
and the scripts are all stored in the same file.

If it's not, you might take a look at one of these other kinds of
products. If you need a cross-platform solution, our product MetaCard
runs on Windows 3.1/95/NT and all popular UNIX platforms, and a Mac
version is in alpha-test. See http://www.metacard.com for more
information and to download the free Starter Kit version.
