// JavaScript File provides functions to build modal dialog window 
// working in both IE and Mozilla
/* 
  Notes: 
    1. edge & help attributes do not work. 
    2. "height" & "width" must be entered before "center" 
    3. if you should choose to set "center=yes" do not put in "left" and "top" 
    4. Minimize button not hidden, but when clicked the window will not disappear 
    5. Aside from the aforementioned, all features should react the same *fingers crossed*
