intercept or halt wizelinks to call ajax when pressing browser back button

[staroflead]

I built an index page with posts, when user click on the post, it's content is displayed on a popup and thanks to wizelinks, it works nice ( with page titlte, address url). However, when I press Chrome 's back button, it invokes ajax call again and renders index page within the popup!

Can you show me how to intercept/ halt wizelinks to call ajax at this point? I just want to close the popup and change back url without invoking wizelinks and load the content.

There is another problem regarding browser back button too, if these 2 be fix, wizelink will be undoubted best history tool around.
First i read a post via ajax request, then F5 to refresh page. browser sends get request to get post content again ( showing full template and layout), then I press back button, it call last page via Ajax, which will render nothing because lack of container div in my posts/show page.
Is there a way to do history.back(-1) normally for this case?
