Some of our users told us that often they have to click two or more times to access viewforum or viewtopic
They said it happens with IE 6.
This doesn't happen with Firefox.
I tested this "bug" and it exist with IE.
Sometimes, if I am in viewtopic and click browser's back button (so I am in viewforum) I click on topic title but the page never loads.
I think it's related to the script (I suppose JS) that causes that all the cell <td> is a link, not only the title in the cell, like other standard forums.
