Hi,
I'm using K2 in a website joomla 2,5 and i'm against some kind of a problem:

When i'm managing the content of an article and want to put a new image in the PLG _K2_YJK2_SLIDER, as i select one, it go to a media manager page and has i have selected one image, it don't want to validate it.
It's simply blocked on this page and it don't want to put the image or to cancel it.

the "insert" button and the "cancel" button does not work

Can someone help?

Thanks
