Hi everyone,

This issue is really driving me crazy.
I have very simple code that runs at the beginning of my application, it calculates number of records that are locked in a table and when it riches the end it will add a new record place a lock on this record and exit. It also might a record which is not locked, then instead adding a new record it will use this record to place a lock.
Here is the code

SELECT UserCount
lnReprocess = SET("REPROCESS")
*--repeat attempt to lock once
SET REPROCESS TO 1 
pnLocRecord=0
pnactivecount=0
*-- pnMaxUsers = 5
FOR i = 1 TO pnMaxUsers
    IF EOF()
        APPEND BLANK
    ENDIF
    IF RLOCK()
       *--save locked record
       pnLocRecord=RECNO()
       EXIT
   ELSE
       pnactivecount=pnactivecount+1
   ENDIF
   SKIP
NEXT
SET REPROCESS TO (lnReprocess)

Today I have a user reporting an issue when the process hangs.
It only involves two particular machines. If one of the machine is already logged in into the system the other one will hang on the RLOCK() statement. Both machines are running Vista OS.
Any one has any idea is to what can be the problem here?

Thank you
Yelena
