I tried all solutions mentioned her, but I cannot get the vertical scroll-bar to disappear in IE and Chrome.
Inserted scrolling:"no" into the iframe, applied various versions of overflow: hidden to body, iframe or form div (tried without form div too, also instead of hidden auto).
Interesting: this sample has a form within the iframe. When I use a different url in the iframe, no scroll-bar shows.
What am I doing wrong?
