>Using the same VFP application session, I can duplicate your observations. However, if I open 2 instances of VFP, reprocess works correctly. I don't know if this is a bug or by design. The following code will reproduce your observations:

>oSession = newobject('session')
>set datasession to oSession.DataSessionID
>set exclusive off
>set multilocks on
>set reprocess to 10 seconds
>use some_table

Interesting note to your code, Mark.

If from the command window, after the above code has been run, you type "FLOCK()" it returns .T.

It never did in code, even if I waited (=INKEY(.5)) or did multiple FLOCK() commands. Only from the command window.

What's up with that???????
