When placing the category menu on the buy now page, category 1 always recieves the "SelectedNodeStyle" class in the TreeView regardless of what category I am viewing. 

I can choose another category, at which point the new category breifly recieves the selected class, but the page then reloads and category 1 again recieves the SelectedNodeStyle class, leaving the user the impression that they are still viewing this category, even though the product listing has now updated.

Thanks for any help,

Craig
