Ave,

Interesting.
I did get this JavaScript code for OS detection:

// This script sets OSName variable as follows:
// "Windows" for all versions of Windows
// "MacOS" for all versions of Macintosh OS
// "Linux" for all versions of Linux
// "UNIX" for all other UNIX flavors
// "Unknown OS" indicates failure to detect the OS

var OSName="Unknown OS";
if (navigator.appVersion.indexOf("Win")!=-1) OSName="Windows";
if (navigator.appVersion.indexOf("Mac")!=-1) OSName="MacOS";
if (navigator.appVersion.indexOf("X11")!=-1) OSName="UNIX";
if (navigator.appVersion.indexOf("Linux")!=-1) OSName="Linux";

document.write('Your OS: '+OSName);

Which does serve my purpose. I guess I'll work something with this out.

Thanks.
