Close pop-up after a PDF is loaded in parent

[darkdragon76]

I am trying to close a pop-up window after a PDF is loaded in the parent window.

Parent Window:
1. load an html page (JSP)
2. pop-up a new window
3. call a PDF to open in this window
(actually calls a servlet that calls the PDF)

Child Window:
1. sits on top of the Parent Window
2. needs to be closed when the PDF is finished loading

Any ideas? Note, this is for an IE 5.5 version browser only, but can't use any ActiveX controls.

Thanks for any help!
