Add Media, Choose file to uplaod not active anymore

Hi all

We and my friend Mik, have been running our blog successfully for some time. But all of a sudden, the media uploader refuse to work any more ?!!

When we want to uplaod an image, the window showing up integrates only a button Choose your File, which you can click as mush as you want, nothing happens.

What I saw, is when this window is showing up, there is a Browse field that appears and desappears quickly to be replaced by this button Choose your file ?

I tried to deactivate the plugins, nothing do. I clean my browser cache and history, nothing.

But what is strange, it does exactly the same to my friend Mik.

He is using IE, whereas I am using Firefox. So it is not a browser problem.

Why all of a sudden the media refuses to work, this is a mystery !

ok, I try today to upgrade to 2.7 we will see.

But anybody as a clue about such a behavior. I searched the forum but did not find anything alike.

Thanks in Advance
Olivier
