Easyblog page keeps loading and loading

Hi,

When opening a easyblog page on our website, for example http://uwassistent.nl/blogs/persoonlijke-ervaring, it keeps loading the whole time. And it adds ?wmode=transparent behind the url, so you get http://uwassistent.nl/blogs/persoonlijke-ervaring?wmode=transparent

I'm unfamiliar with this problem. Maybe someone knows the solution to this problem?

Thanks in advance!

Geert
