Yes, they've always refreshed fine by themselves, because of the rel's set up in the DE. I just can't get the middle grid to highlight when I leave it. At least I've stopped the "bouncing" cursor on the middle grid. The AfterRowColChange code now stands as follows:

* Need this bit to filter the data in the child grid of this
Select pxCOMPLETE
lnFacCatCode	= FACCATCODE

Select FACDESC	
If EMPTY( lnFacCatCode)
    Set Filter To 
Else
    lcFilter	= "FAC_CAT_CODE = " + ALLTRIM( STR( lnFacCatCode)) + ;
		  " OR EMPTY( FAC_CAT_CODE)"
    Set Filter To &lcFilter 
Endif 
Locate

Select pxCOMPLETE

This.Refresh()          && Only place I can think of to force a refresh here.
Thisform.LockScreen		= .F.

Can you see anything I'm missing?
Cheers

Terry
