ERROR -354 in VB -> Q+E ODBC -> INFORMIX 6.0 SQL

Hi Folks, This is a very interesting problem that i am facing. My client is Windows 3.11 /16MB and running an application written in VB accessing Informix 6.0 using Q+E Informix ODBC drivers on TCP/IP. The four statments that are called from my VB code are as follows, all of them are dynasets : T1 = select count(*) from Table1 A = select name from Table2 where col1 = 1 B = select col1 from Table3 (*** - No where clause) C = select name from Table4 The sequence of execution in my code is T1 then A then B then C then T1 which is when it raises the error -354 which according to the manual is Incorrect cursor or database name. The same problem does not happen if i close the dynaset associated with A before i execute T1 again. Is this error number misleading ? The entire set of onstat options have been exhausted for this scenario ( -g sql, -glo , -act, -ses ..) Is there are parameter which can be fine-tuned to solve this? TIA, Venki
