Hello BHunt:
If the end user's PCs don't have Visual COBOL installed, then what *do* they have?
In order to run programs compiled with Visual COBOL, an end-user PC should have the Micro Focus runtime product corresponding to the version of Visual COBOL. For example if the programs were compiled using Visual COBOL version 2.2, then end-user PCs should have the product named COBOL Server version 2.2.
If the end-user PCs have an older version of Micro Focus, it could cause "undefined behavior" including possibly the symptoms you describe.
