Data Binding Problem

I have an ADO data control with a grid and textboxes bound to it.  Everything works fine when running XP, but when running 2000, the grid retrieves the data but the textboxes don't.

   With mconnTest
      .CursorLocation = adUseServer
      .ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
                          "Persist Security Info=False;" & _
                          "Data Source=" & DatabaseName()
      .Mode = adModeReadWrite
      .Open
   End With

   mrsTimecards.Open "SELECT * FROM Timecards", mconnTest, adOpenKeyset, adLockOptimistic

   Set datTimecards.Recordset = mrsTimecards
   datTimecards.Recordset.Requery


I also tried bypassing the data control and binding the controls directly to the recordset:

   Set grdTimecards.DataSource = mrsTimecards

   Set txtEmployeeName.DataSource = mrsTimecards

   txtEmployeeName.DataField = "EmployeeName"

which also works with XP but not with 2000.  I have service packed 2000 and installed the latest MDAC and Jet Components.  Still no dice.

MSADODC.OCX and MSBIND.DLL have been installed and registered.

I have also tried using a client-side cursor with no luck.
