Plugin does not work on article pages

Hello author. I’ve installed your plugin Float Ads Fixed Position and it works well only on the main page and category pages. For example like here:
http://www.usualhouse.com
and here
http://www.usualhouse.com/?cat=184

But if I load any of article page, your plugin do not works correctly. Banners does not float when I scrolling down the page. Take a look for example this page:
http://www.usualhouse.com/?p=7035
Try to scroll down the page and you’ll see.

I think this is not entirely correct. I think that the plugin should work on all pages of site. If you agree with me, please fix this bug.
Waiting for your reply.
Thanx
