Problem with VM2 Seo and Hotscroller = no Facebox

Hello,
excuse my bad english

Wen i use Virtuemart 2.0.18 and Hotscroller the Facebox dont show up, wen i buy a Product.
I activate Joomla/Virtuemart Seo, all works fine.
Now i try to buy a product and press on the "add to card" button, normaly a facebox pops.
But with activated Hotscroller Module it wont popup, only if i disable the Hotscroller Module.

Can anybody help me to get Hotscroller working with the Joomla/Vm Seo ?

Thank you !
