Using VFP 6 and VMF 4

I am using a subclass of frmdataentry. After I alias the main table(mmorg) in the load event the pointer no longer moves in the main table after an addition and a save. It does move in the aliased table. Here are the properties I have set.

THISFORM.icMainAlias = mmorg

Code in Load to alias the table
.oDBCSvc.OpenAppTable("mmorg",,,"mmorg_parsub")

I use the alias table for a picklist control on the form. If I remove the control and the alias code the pointer does move in mmorg properly. Why would aliasing the table make the pointer not move in mmorg?

Thank you,
