You can run WO-J on other workstations?  If you have older Pervasive (before PSQL 9) or a newer version but did not change the setting for file size greater than 2 GB, then the behavior you are describing (close back to the menu without actually doing what the program was trying to do) will occur if there is a file greater than 2GB in the set of files the program is trying to write to.  However, this will be all workstations, not just 1.
