I am rebuilding a website and it includes a Flash header that I did not build. As far as I can tell, something about the flash is causing the problem, because when I remove the code to put it in the site is fine.

Shortly after the Flash finishes, the website is opened again in another tab. (In this case the original is opened from the test site)

Here is the link with the flash:
and without:

If anyone could help, that would be great!
