Adding graphics in MCQ and Quizzes

I am working with 3.5, but as I remember a part of this bug is also popping up in
earlier versions.

When I add a picture from the right-sided menu in a MCQ or Quiz, the buttons Next,
restart, etc will not be places at a proper position on the page (see attached
knipsel2.png)

When I add a picture in a Quiz page with help of the WYSIWYG editor, the answers are placed over the picture. See attached knipsel1.png). Strange enough one of the quiz-questions behaves well . See attached knipsel3.png.

Any idea to solve this?

<Adding attachments does not work for me here >

Now in JPG... In png it does noet work.

Oops, I solved a part of the error myself. When you use the WYSIWYG editor set the alignment at None. I used Left. That does not work.

The other problem still exists. Adding an image with the menu at the right, the buttons are placed over the image.
