First of all thanks to Eric MArtin for SimpleModal.
I've started using it developing in mac environment. When i loaded to my hosting server and then checked the results in IE, the overlay completely ignores the embedded iframe in my page. It appears as if the iframe has a higher Zindex than anything else on the page, so i checked. Well firstly simplemodal works fine in Safari and Opera and everything is layered correctly. However in Firefox and IE (using 7 and 8 to check) the iframe is not overlayed.
I also set the zindex property to 9000 to check. Nothing doing. I've dug around simplemoda, the net etc and cannot get any hints on CSS properties that might be used to overcome it.
Any ideas on what is happening anyone.
