Jack,
Did you ever determine what was causing this?

>With Windows-98 and WordPerfect 8, the following code works fine in VFP 6.0a, but fails after the third or fourth iteration in VFP 7.0 SP1 and 8.0. Note that on Windows-2000, all three versions of VFP may yield the error "Server threw an Exception" after three or four iterations (this error can be apparently be ignored with impunity; the error on Windows 98 will recur if ignored).
>
>Note that closing VFP and reopening resolves the problem (at least for another three or four iterations). It also happens when I build an EXE and run it. I have also tried adding DOEVENTS with no effect.
