Make sure that all the aliases in that DS are really closed, =tablerevert() them as needed (or all the buffered ones). Happens in the command window - I can imagine it would happen in runtime as well. We're actually pampered by VFP's doing this sort of garbage collection for us, closing the tables for us when we quit.
