That is NOT due to the use of encryption, BUT instead that
Acrobat 6 no longer runs JavaScripts in a document that is encrypted
BUT without "form filling" rights enabled.

Hello Leonard,

thanks for your answer.
I tried out, but that's not the reason :-(

When I have an encrypted document without Javascripts, everything is fine. When I encrypt one with Javascript, then Adobe Reader 6 ignores it and Acrobat 5 crashes.
In my decrypter function I can decrypt every string. When I create a Pdf with Adobe Acrobat, then I can decrypt every string in the whole document (I know the owner PW) but not the Javascript Part. Every test I do, it seems the Javascript Part has done with an different encryption code.
Is there any Specification about this in the web? In the Adobe Pdf Spec I didn't find anything about it.

Thanks everyone for help.

Roman
