Barbara,

Thanks for both of your responses (and please see my reply to Ed).

>In one app we had a semaphore table that was used to 'lock' certain functions. We found that it would take as much as 15 minutes after WorkStation 1 had added a semaphore record before it was available on WorkStation 2, even though WS2 opened the table with USE Semaphore for each call to the function. No adjusting of SET REFRESH worked.

good info....J
