I am getting the following error on some of the computerer at my client's office. I am using VFP9. Only a few of the computers are having problems with this query.

   Too many subqueries.

The offending code is:

	LEFT Join tmpfrequency N On a.sif_no = N.sif_no ;
	LEFT Join tmpExp_mod o On a.sif_no = o.sif_no ;
	Into Cursor tmpagg Readwrite

Anyone have any ideas why this creates an error in some of the computers and not the other. This is a VFP 9 application.
Thanks
