I'm happy if my message gave you the hint you needed to track down the wrong settings.

>>>Hello,
>>>
>>>I have had several issues with index corruptions and wrong unique keys. Now I have seen that the reason for these problems is how VFP reads the data on the network on two particular machines (XP).
>>>
>>>The following scenario:

>>>*-- Machine 1:
>>>USE N:\Cinema\PrimKey
>>>?prNumber && returns 11600
>>>
>>>*-- Machine 2:
>>>USE N:\Cinema\PrimKey
>>>?prNumber && Shows 11610
>>>REPLACE prNumber WITH 11611
>>>?prNumber && Shows 11611
>>>
>>>*-- Machine1:
>>>?prNumber && still shows 11600 !
>>>

>>>In fact, machine 1 does not show the updated numbers, until I reboot the entire computer. After reboot, VFP reads the updated values, but then again stucks on those values until rebooted.
>>>
>>>Only VFP has that problem, when accessed with another program, the values are uptodate.
>>>
>>>What could be the reason for that and how can I solve that?
>>>
>>>I tried SET REFRESH TO 1, Flush IN after every replace, and do record lock (and sometimes file lock) whenever appropriate.
>>>
>>>Thank you for your help in advance.
