When I link from one PDF to the other via "open a file" function (both PDFs are located in %userprofile%/mydocuments directory), Reader X and XI open a security warning box. If I agree to open the target file, this specific file always opens without displaying the warning again.
When I link to the same file via app.opendoc, the security warning box does not open. So I do not get a chance to add the target file to the list of trusted files.
Is there any way to motivate app.opendoc to display security warning boxes due to the new sandboxing technology in Reader >= X? So that I get a chance to add the target PDF to the trusted PDFs?
