thank you for the answer, which is quite helpful but not working with the Browsers Zoom setting.
On windows(chrome,ie9,ff...) you can just hold ctrl and use the mouse wheel to zoom in/out for example.
Is that the Flex appl also get zoomed in/out that way ?
But thankls again thats a very good alternative for the browser zoom.
how could I realize a scaling Flex page which make use of the Browser Scale option ?
In windows it would be ctrl+mousewheel and on OS X Apple & +/-
My Flex app needs an overlaying iFrame which need to get resized aswell.
