XUL toolbar not showing :(

I have developed a basic toolbar (1 button). the install runs fine, but the toolbar does not show. I took most of the code from a DevEdge example and modified it for my own needs. Anyone have any ideas here? There should be a menu option in the Show/Hide menu as well, but nothing there either. I have attached the .xpi file in a ZIP(there is nothing malicious here, cheeck it for yourself if you have to). Any help here would be greatly appreciated.

You're missing a </hbox> in PLPtoolbarOverlay.xul I think that's the problem. I havn't even messed w/ overlays and stuff yet.

Okay, I've got the display figured out. What I need now is to return the selected text in the browser window. I have tried the javascript window.getSelected(), but that returns a blank (I guess it is looking at the wrong window). What reference can I make here? I ned to pass this selected text to an EXE on the client machine, so URL parsing might not be the way to go.

Now have the passing if the selected text figured out. Calling the EXE is now the problem. Javascript under IE has the ActiveXObject method to create an instance of a DLL (whihc calls the EXE), but Netscape does not seem tosupport this. Any ideas?
