I've created a page which utilizes dynamic page loading with JS, it works fine in Safari, FF and Chrome - But of course the infamous Internet Explorer isn't doing a good job.
(I know there are other issues on this page, under the "Cykler" section, these aren't important for this question and shouldn't be focused at)
Try clicking on one of the categories, Cykler, Info and so on.
The strange thing is that if I open developer tools in IE and set the mode to IE8 and back to IE9 there is no issue, it switches pages like any of the other browsers.
If I close and open IE again the issue is back - If I go to the console to check what's going on it asks me to refresh the page - When I do this the issue is gone again.
I have no idea what the heck is going on, two of my friends have tested as well and they both have the issue when coming to the page for the first time.
