Thanks for all the help.  Geoff's suggestion did the trick:

Open the file locally with full access (no server) on both platforms. Make the window the way you want it, and then go into define fields. You don’t actually have to define a field, but you have to do enough to make FileMaker save the window info into the file.

Thanks again, getting harder and harder to find help for this ancient version of Filemaker Pro and Filemaker Pro Server.
