	That does sound rather a long time. Check the driver options to see
if logging is enable. Also check to see if ODBC is tracing. Make sure both
these options are of. Also unles you use the fetch option I *think* the ODBC
driver will just try and upload the entire result of the query (which will
take a loooong time if you don't have a where clause on a million row
table). When you say changing text box source do you mean the text boxes
Control Source or the actual data? Do both take a long time or only one?
What is the Record Source for the form? Is it a passthrough query or a
linked table? Also if its based on a join, MS Access joins a slow. For help
on ODBC problems there is a mailing list on
Hope this helps,
