If you're developing an Adobe Reader plugin, you have dedicated support as part of your Reader Integration Key package. Please direct your support requests via the contact details provided with that package, not to the Adobe Reader forum (which is here to support end users, not developers).
Thanks for the quick response Dave. Appreciate it.
However, this plug-in was developed long back and has been working just fine all along until the Protected Mode was brought in recently with Reader X. Since the forum talks big about the custom policy implementation, thought someone would be able to help. Hence that forum post. Let me know if some help can be provided on the custom policy implementation to be able to make the plug-ins work out of the box without code changes.
We don't have a Reader SDK topic. You can try asking in the Acrobat SDK topic, but as I said the best route to support for Reader plugin developers is not via these forums.
There's some limited information in the Acrobat X SDK documentation, including a sample of how to fire up a broker process.
