Inserting a gallery of full-frame photos

With my WP 2.7 blog I could “insert” a gallery of photos into a posting. I have posted 30-50 photos with one click on the insert button. NOW, on 3.0.1, I have to insert each (960 x 540) photo one at a time.
What once took a second now takes 30 minutes. The only way I can insert an entire gallery with one click is with thumbnails.

Go to this link. This is what I see at the base of my media library.

All I get is thumbnails. I CANNOT insert the photos as full frame photos. They are 960×540

What seems so strange is on 2.7 this uploading worked flawlessly,
now 3.0.1 is messed up.
