CP9 project freezes after opening a MS Word document link.

The project plays fine until the slide where there is a link to open a word document in a different window.  If you open the link  then come back to the CP9 project the project will not advance.  The playbar doesn't show a play arrow like it normally does when you pause a project.  This project ignores  the forward arrow and table of contents to move forward.  If you don't open the MS Word document link then the forward arrow works but there still isn't a play arrow on the play bar.  This is being hosted on a web server.

Thanks in advance for any help.
