RDO and ODBC API Problem

Hello

I am using VB5.0 , RDO2.0 in my application, which now has two forms. The first form has a TDBGrid and is in display only. The second form has two Tdbgrid in updatable mode. I have used Native ODBC API calls for database access for the first form and RDO in the second form. This is done due to performance requirement.

The problem I face now is that whenever I open the second form, change field values and try to update database the RDO returns an error :> "S1011 : Operation not valid at this time". I have freed every acquired ODBC handle before opening the second form and there is absolutely no dependency between the forms.


Somebody please give me a explanation and/or solution to this problem.


Thanks
