What is it: Fortis is a windowing environment that runs in a single
dynamic IE DHTML page. It can be used by itself or with
other page components as it is minimally intrusive. It boasts
a window bar (like in MS Windows 9x), global menu and status
bar, and windows that can contain other (arbitrary) web pages.
It can be used for easily creating web applications, either
by generating API calls and windows content on the fly from a
server, for static client-server applicatins, or for
client-only solutions. For more information and documentation

Installation: add these elements to your page anywhere within your BODY
tag and before your code.
var MAXWIN = 100;
for(var i = 0; i < MAXWIN; i++)
document.write('<DIV ID="FORTIS_W'+ i +'" STYLE="position: absolute"></DIV>');
The value of MAXWIN determines the maximum number of windows that
can be created. Change it at will, but a very large number will slow
down page loading.
You may want to adjust the URL for the modules if they reside in a
different directory than your page.
