Hi Agnes,

at the time I only see one difference between your approach and the one that I am working with.
My call is like this:

 MODIFY REPORT (m.vFile) NOENVIRONMENT PROTECTED SAVE

Although our customers get access to create/modify individuals reports, we never save the dataenvironment with the default report and it will always run in protected mode. BTW the MODI REPO is called from within a small exe which receives just one parameter and that's the frx including the path. If the parameter can be validated, there are some SET commands like path, reportbehavior and sysmenu and then the above mentioned modi repo.
Looking at your code, to me it isn't obvious why it doesn't behave the way it should. Oh, and we don't use foxuser.dbf...
