Content disappears

when I leave a window with flash content, in this case, a scrolling movie clip with buttons inside set to hyperlink popups (only 1 hyperlink is set so far):

http://www.carlsonmedia.tv/new3/print.html

the flash content will disappear. So if I go back to the window, I have to reload the page to get the flash to appear again.

Same thing happens if I minimize the window, when I bring it back up, no flash, and I have to reload the page.

The menubar with the boxes at the top is flash as well (different swf) and that doesn’t have this problem.

Anyone have an idea what I’m doing wrong?

EDIT: specifically, the first image in the scrolling flash pane links to a popup window. If you MOVE the popup window, the flash content in the first page dissapears.
