The latest version of Safari for both the Mac and Windows do NOT like calls to the API.
On a Mac, the pop-ups always open behind the calling browser. In Windows, the calling browsers jerks a few pixels like a hiccup, but no Pretty Photo window opens.
Using the latest ver. of Jquery.
Note that, these calls are being made from links within an XML file that is loaded into Falsh.
The following work flawlessly in Opera, FireFox, and MSIE, but NOT Safari:
function doQuickTimeVideoTwo() // user-defined function example
{
var contentState="isOpen"; // do not remove
notifyFlash(contentState); // do not remove
