It appears that Form 2 is using the DBC in the \\data_directory rather than the one in the \\users\personal directory -- but they are truly identical since one is a copy-and-paste of the other. Form 2 wouldn't work until I copied the DBC to \\data_directory.

There is no Set Path anywhere in the app but there is an oApp property that holds the path to the \\users\personal copy of the DBC. This is only used with the Open Database command. Prodata.DBC is opened explicitly upon startup as well from a path stored in an oApp property.

I've actually tried calling the OpenDatabase routine that opens both DBCs from the Init() of Form 2 but it doesn't seem to make any difference.
