Problems with Wordpress 2.6

I recently installed 2.6 and Is already making me problems, here is the pic:


When I make new post, I usually make three thumbnail pictures In center, in the same line. In wp 2.6 I can't do that. The pictures go under each one, I don't know why, can anyone help me?

 

When you click insert image into post from the Gallery each image is inserted in a new line. Simply put all the tags in the same line and you should get the images in a single line.

 

How do I do that? You mean the tags that are under the picture? (alt title).
