Power Point Viewer 2003/2007 - stuck on a black screen

Hello,
I have built a Presentation using PowerPoint 2003. After finishing the
presentation, I click on Package CD from the file menu to publish the
presentation.
The presentation contains sub presentations (it was built in modular way).
To navigate between the divers presentations, I am using the hyperlinks.

I saw that the presentation intermittently become Non-Responsive (i.e.
Getting “Stuck� with “Black Screen�) when double left clicking on a link or
when using the “Escape� keyboard button repeatedly to close & exit the open
Presentations. I think that there is a problem in the powerpoint viewer 2003
(it also appears in the ppviewer 2007). When I am running the presentation
from the powerpoint 2003 (not viewer), the problem doesn't appear.

Thanks for help
