I have followed the Tutorial on this site for the <B>Chromeless windows</B> javascript with success, except it seems that it does not work on Mac OS, only PC. Can anyone tell me if it is possible to achieve the same effect for both platforms?
No, they can not work on Macs.
In fact…
Chromeless windows don’t work in IE6 SP1 anymore either. This means that as of IE6 SP1, Chromeless windows are dead. No other browser supported Chromeless windows, so it was only IE, but not it is no longer IE. Chromeless windows will not launch as full screen windows in the new IE, Microbians (the company who made this script) released a patch to this problem by creating a normal old pop-up like what appears in all other browsers, but this patch had a serious bug that caused the windows that contained the link that launched the Chromeless window to become white with the text [object], so they removed the patch.
