>Well, yes, I realize that, but this is just VFP doing its thing and writing whatever it wants to write to the FOXUSER table. Actually, I could probably SET RESOURCE OFF, however I just never did this and there's no great advantage or disadvantage to it (until now <g>).

If I understand you correctly, you do not work in the code with foxuser. If it is the case, then most likely foxuser is in the directory where user has limited privileges (even it is on the user PC, user may have read-only access to the directory or particular files).
