Insert image menu not working #2!

Hi,

I am having the exact same problem as dearteco, in his post with the same title as this post.

When clicking on a thumbnail in the upload section of a post, the image menu with ‘use thumbnail’, ‘send to editor’ etc doesn’t pop up! Dragging is still possible, but I want my image set to ‘use original’ for bigger display.

Who knows what is going on?

Thanks,
Marije
