I'm using IE7. I have included an image in my content panel which exceeds the normal height and width of page. In the view mode there is an extra vertical scroll bar other than the usual one. But its good in IE8 and Firefox.
The following are the height and width of my layout panels.
Content Panel - Height=Auto/Width=100%/Overflow=Auto
Page - Height=Auto/Width=Auto/Overflow=Auto
Document - Height=Auto/Width=Auto/Overflow=Auto
