Image carousel bug in IE

Hi,
I have a script error in Internet explorer 9 when the mediaplayer is displayed with a image carroussel on the same page.
If I remove in /www/misc/jquery.js the code in line 139 :
b.username?w.open(h,b.url,b.async,b.username,b.password):w.open(h,b.url,b.async)
the page is OK.
As I can remove the code from the Drupal install can you help me to find a solution.
Best Regards,
