[SOLVED]image of the product obscures the menu

[ViewSonic]

Hello everyone,

First of all - sorry for my English.

I am trying to solve problem with an image of the product which obscures the menu.
To understand what i mean please take a look on this image:

As you can notice when i enter a product page
and i move mouse cursor on my image product everything looks OK. But after that when i try to select another category of the product for example "Odziez skorzana" you will see that the menu is poping up but it can't be seen because the image of the previous product obscures this menu.

Could you tell me what i should do to fix the problem or at least which file is responsible for it ? is it product.tpl ?

I used cloud zoom script from this website http://www.professorcloud.com/mainsite/cloud-zoom-integration.htm
and i made changes accordingly to this thread
http://www.prestashop.com/forums/viewthread/80420/development/modification_of_the_prestashop_zoom_function


When i disable jqzoom in Back Office >> Preferences >> Products and the image is shown in thickbox everything works fine. I supposse that i have to change something in cloud zoom script but i'm not sure. Maybe i have to change something near mouseevent code

thank you


EDIT:
Problem solved - z-index was on 9999 i change i to 10 and now it's OK
