Anyone good with cakeslice?

Ok so i just got myself cakeslice.

I have cropped a 2 page submit form but it crops the first signup fine, but when it comes time to the second page, the frame is off and it does not line up correctly.

I have tried to enable scrolling on the iframe but because of the way the first sign up page and the second sign up pages are designed on the second sign up form, the top half gets cut off and i can only scroll down.

Any ideas?
