Acrobat Plugin Unloading

Question

When closing Adobe Acrobat after using my plugin it throws an error.
I release all my objects ( I Think ) when the following method is called
ACCB1 ASBool ACCB2 PluginUnload ()
But still get the error.
The part which seems to be the problem is the following lines of code
  std::string str ("C:\\test.jpg");
                              asPathName = ASFileSysCreatePathName(NULL, ASAtomFromString("Cstring"), str.c_str(), 0);
                              if(ASFileSysOpenFile64(0, asPathName, ASFILE_READ, (ASFile *)&asFile) != 0)
      AVAlertNote("Could not read file...");
      bRet = false;
      return bRet;
                              *outNumASPathNames = 1;
                              *outASPathNames = (ASPathName*)&asPathName;
                              *ioChosenFilterIndex = -1;
                              *outFileSys = ASGetDefaultFileSys();
This is returning successfully and inserting a Document (test.jpg) into the current PDF.
Later on in my Cleanup code I release everything I can tell.
  ASFileSysReleasePath(0,asPathName);
          asFile = NULL;
From the Adobe SDK API it only says I need to release the ASPathName, Am I missing something here?

Hi,
Thanks.
So I want to make sure this is because with Acrobat 9 - the new way to deal with PDF's?  Because as per my knowledge it was working fine with Acrobat 8.
Moreover, if I am understanding correctly and I have tested too, the order is important here, right? If I will load PDF in IE first and then I will work on my web site it is not creating problem but if I will launch my web site first and then open PDF within IE in different tab it is creating problem because they are using same interface and when AcroPDF instantiating overriding and failed to load plug_in
Here I have seen that both Acrobat.exe and AcroPDF.dll is using same Acrobat.dll pointing to same memory addresses and that's why problem is happening.
IT would be great if you can provide any other way to "hook" adobe because the bottom line I have to use AcroExch.App from SDK.
One last question, I have seen that if I am opening a PDF in Internet Explorer in a different tab (not in my web app) while pressing SHIFT key and the move to my web site and load different document it is working fine, so the question is what different is happening when we open PDF in IE with pressing SHIFT key and without pressing SHIFT key. IS AcroPDF.dll behaves differently while opening PDF with SHIFT key pressed?
Thanks for all your help.
