Steps to Reproduce Behavior

1. Confirm that file sharing is enabled by clicking the Apple menu, 

   choosing Control Panels, and then selecting Sharing Setup.
2. Create and run the following program: 

   SET STATUS ON
   USE SYS(2004)+"Tutorial:Customer.dbf" SHARED
   SET MULTILOCKS ON
   DO WHILE !EOF() AND RLOCK()
      SKIP
   ENDDO
3. After record 220 is locked, the message "Attempting to lock... Press ESC 
   to Cancel" appears briefly in a Wait Window, and then the program
   terminates. The status bar displays Record: 221/500 Record Unlocked
