Thank you, Sandy. This web page did have the answer. I had visited that
site earlier during my approximately eight hours of searching for this
information, but had missed that particular page. One mouse click on the
correct radio button got rid of the problem. Another example of how simple
these things are WHEN YOU KNOW. Thanks again.

I'm having the same problem with my video clips playing full screen over the
text. I had trouble locating the link that Sandy provided. If possible,
could you list the steps I need to take to avoid this problem? Thanks!

Update: I exercised a little more patience and figured it out. Thanks for
pointing me in the right direction.

Scott, sounds as if you were able to locate the "Overlay" tab buried in the
deepest recesses of the Display portion of the operating system. Until I
ran into this problem I knew nothing about all these somewhat hidden
features but the experience taught me a lot about comuter systems and also
how effective the Intenet is in making readily available the accumulated
knowledge of people all around the world. Glad you were able to find a
solution.
