Add image in a post in wp 2,5

I can not add an image in my posts after I upgrade to wordpress 2,5. I have swedish as language.
I have on html view and I choice from my hard drive but it stand: “the selected file didn’t manage the uploadtest”.
The window i get up to upload imagen is very low in my webb window.. can’t get it higher.

I have take a printscreen but I can not see where I can upload it here.
