Recently installed the Upgraded IFrame module and am using the CSS Autoheight trick (works just fine).  The problem is when the content inside the Iframe expands the width of the page..the page does not expand to show the entire width of the IFrame contents, instead there is a horizontal scrollbar.  I know for a fact that my skin can have it's width expanded because all attributes are set to percentages, not specific pixels.  Also, I have the EpiFrame module which resizes the width of the page just fine when the content of the Iframe changes, but there is a horizontal scroll bar with this IFrame module when the width of Iframe contents are larger than the width of the page.  Any reason for this occuring and what can I do to fix it?  Thanks so much!  (I'm trying to stay away from EpiFrame because it required web.config modification that effects other modules)

'100%' for the width seems to work.
What is the height trick? I am stuck on that.
