Ken,

Could you putting code in the Grid's Refresh() instead?

ThisForm.myButton.Visible = ( RECCOUNT( This.RecordSource ) > 0 )

Another thing I noticed in your code:

THIS.VISIBLE = RECCOUNT('cCustList') > 0 

Should'nt parentheses be used, like so:

THIS.VISIBLE = ( RECCOUNT('cCustList') > 0 )

Hope to help.
