I really don't like this forum

This has happened to me so many times, and I don't know why I continue doing it. I write long posts, and then add pictures. After I add the fourth picture the thing freezes, and it says Inserting image... for a long time. The only thing I can do is reload the page, but my long post would be all gone. :/ There should be a way to close that Inserting image... box.

It really has something against this picture. It doesn't add it from a link or when I save it to my computer.
