Most users of Reader will not be knowledgeable enough to help you. Post in the Acrobat SDK forum. Those users are better able to help you.
Thanks you very much Michael.
I was searching for Acrobat SDK forum earlier today but couldn't find it.
Can you please send me a link?

Due to the restrictions of the protected mode (sandbox) process, it is not possible for plugin code to SendMessage/PostMessage to windows not belong to the sandbox process. Also, configurable whitelists currently have no rule that allows such cross-process message sending.
If the other application and the Reader plugin are both under your control (cooperative), you could implement the inter-process communication via some means (other than windows messages) like named pipes or shared memory and add custom rules in the configurable whitelist file to enable access to these specific pipe or section objects.
