Error with MSAccess97 subforms and PostODBC

Here's an extract of a log of the postODBC driver on the machine I'm
running MSAccess 97 on.

I've got a form with two dependant subforms in it and when I add a new
record, I get two ODBC errors because the two subforms are looking for a
linked field named "IDC" that's currently NULL since it's a new record and
an ID has not yet been assigned. Here's what's happening on my system:

==============

Tabs have got screwed up beacuse I pasted the text from another machine.

Let me know if there's anybody who knows a workaround for this one.
