Smilies aren't clickable

[Blobber]

I have a problem adding smilies to a post because you can't click on them.
However the weird thing is that when i press "Preview Post" and then edit the message they are clickable.

I tried to figure out what the problem is but it seems i have the problem also with the default skin.
