Drop field not calling Div for accept

[CaseyR]

Hi, All

I have a strange problem with a drop control on a form not calling the DIV when accepted, and hence not calling the Validate routine or refreshing any of the conditional controls on the form.  On the browser,  the drop displays the selection properly.

The form itself is a very complex using an In-Memory table with lots of controls that refresh others on acceptance.  All the other controls works as expected.

Even the problem drop control works if an existing set of physical records are loaded into the In-Memory record first.  Priming the drop field and setting the SessionValue  for a new record didn't fix the problem.  I have systematically gone through all the combinations for immediate validation on both the form and the specific field.

Using NT 7.31 but I don't see anything in the newer releases that addresses the problem.

Any suggestions even just how to trace the problem gratefully appreciated. 

Thanks.
