problem with dynamic menu

On my website [url]Maridon - Maridon I have the css drop down menu and the dynamic menu enabled. When I click on a category on the drop down menu the subcategories from the parent category are showed correctly. When I click on the “home” button (the logo) the dynamic menu is still expanded. Does anyone know how I can fix this?

I don’t know if this is a bug or not but I would post a helpdesk ticket or post a bug in the bug tracker, Thanks - Sno
