I am running Vista Home Premium (SP1) on my box. I do frequent MS updates
and install all updates suggested.

I often click on news clip videos at yahoo and suddenly my computer will not
play them. The IE7 window opens as usual and displays the video field and
video summery and a list of suggested news videos to click on next, the same
as it always has. It just does not play it. I click on the play button and
it still does not play. I made no changes to my computer that I am aware
of. I do not recall installing any software that would interfere with
video.

Here is a quirk. I installed a trial of tradestation software that has
links to training videos for tradestation. I click on these links (windows
media player logo in the link) in tradestation and it opens a separate IE7
window and plays the training video in IE7 as it always has. I installed
tradestation 2 momths before I had this problem with yahoo video so it can't
be tradestation. It will play training videos but not yahoo news clip
videos off http://www.yahoo.com/ home page.

Any suggestions on how to figure out how to fix this?

Thanks for the help.
