Overlay module clashes with js of wibiya module

Hello,

I had installed wibiya_for_drupal file provided by wibiya.com and checking its working in Drupal7.

The "share" application button (belonging to addthis.com) on wibiya toolbar is not displaying the lightbox popup when overlay module is enabled. The "share" application popup is displayed when overlay module is disabled.

Please, let me know if there is anything i need to do regarding the above.

Thanks,
Prashanth
