Need help reproducing: jQuery Mobile causes IE's window to hide

Need help reproducing: jQuery Mobile causes IE's window to hide

When I go to or refresh my jQuery Mobile site:
 
 
The IE9 window (or IE8 because I've added it to gradeA) hides behind other open windows every time I refresh the browser window.
 
The site uses:
 
  • jQuery Mobile alpha 3
  • jQuery 1.5.1 RC1 (to allow IE9 use at all with alpha 3)
I cannot reproduce this on http://jquerymobile.com/test with IE9 but I can reproduce it on my own site when I use the JavaScript directly from http://jquerymobile.com/test/js .
 
Please tell me if you can reproduce this issue on my site and if I am doing anything wrong before I submit a bug.
 
Thank you,
Ryan
