iAVS window won't close when I click on it

Whenever I click on a menu item for Avast, such as the iAVS window, the blue menu item will not leave my screen. What is causing this and how can I keep it from happening again? Screenshot included below.

Hi, and welcome to the avast forums.

Could you please try importing the reg file referenced in this post: http://forum.avast.com/index.php?topic=24290.msg199900#msg199900

Thanks
