Popups seem to have no communication with parent chrome...please help

I posted this in "embedding" but no one replied, so am posting here.
I'm using Win 2000 and VS 2003

I've put together a very basic skeleton embedding app...but I'm having 
some issues with it.

I tried to install the plugin from
http://player.virtools.com/downloads/playernetscape3.5.asp.  The popup 
for if I wanted to "install or cancel" came up...then RIGHT after it 
without clicking ANYTHING, another popup came up saying "Installation 
stopped by user. Aborting setup.".  Soooo...why does it think I'm 
aborting the install?  It works like it should in FireFox.  Some return 
value in one of my functions maybe?  I'm not sure where to look from here.

Also, when I'm at www.google.com and I am tring to search for something, 
it brings up the "The information you have entered is to be sent over an 
unencrypted..." box.  If I click "Continue", the box closes out but my 
browser does NOT go anywhere...so it seems that my Gecko class is not 
getting the "go ahead" event from clicking the "Continue" button on the 
modal pop up warning box.  The link between the two seems to be 
broken....now, how to fix?

I can verify that when I click a button on the modal popup box, that my 
nsIWebBrowserChrome::DestroyBrowserWindow () is being called.  In that 
function I'm destroying the nsIBaseWindow associated with the 
nsIWebBrowser and then destroying my HWND.  I am NOT implementing the 
nsIWebBrowserChrome::ShowAsModal () or the 
nsIWebBrowserChrome::ExitModalEventLoop () as I did not really have a 
use for them.

I used both the mfc and win versions of examples for embedding to come 
up with what I have now.  Any and all help is much appreciated.  Thanks 
in advance!
