RE: Drop down list - Modifier
When you access the Modifier for the first time, all of the core resources for the
application dictionary are copied to the forms dictionary from DYNAMICS.DIC. Core
resources include strings, data types and global fields that are used by several parts
of the system. Once core resources have been copied to the Forms dictionary, the
runtime engine will look there first when it retrieves resources from the dictionary.
Any additions or modifications you make to core resources will be stored in the forms
dictionary. The modifications will be accessed automatically when you use Microsoft
Dynamics GP.
I would try copying the DYNAMICS.DIC file as well.
