Hoi ioerg and johnapurdy,
I've tried it out on my server. And everything works fine here now scrollbars in Chrome, Explorer 11, Firefox or Safari.
(iframe src="http://astore.amazon.com/treemousepads-20" width="500" height="450" frameborder="0" style="border:0" scrolling="no")(/iframe) ( ) must be changed in < >. Did you all update to the new Beta version 3.0.0(444) of Hype today??
Strange that this occurs.
In the previous beta version. When I used an iframe the page displayed stayed blanco. But in Hype 2.5 the page was displayed normal.
