why doesn't structured frame maker work?

I've installed framemaker 11 on windows 7, unstructured works as it should but when i turn on the structured function everything looks weird. Some things are huge, like the scroll bar. And others are teeny tiny, like the structure view and element windows. When i minimize or maximize the window some parts disappear, it's like the window moves down and to the right, out of the screen. Also the menus are double, so it's really hard to do anything really.... this isn't a problem in the unstructured framemaker. Can anyone help me, or know any one that could?
