function openwindow(thelocation){
temploc=thelocation
if (!(window.resizeTo&&document.all)&&!(window.resizeTo&&document.getElementById)){
window.open(thelocation)
return
}
win2=window.open("","","scrollbars")
win2.moveTo(0,0)
win2.resizeTo(100,100)
go2()
}
function go2(){
if (winheight>=screen.availHeight-3)
x=0
win2.resizeBy(5,x)
winheight+=5
winsize+=5
if (winsize>=screen.width-5){
win2.location=temploc
winheight=100
winsize=100
x=5
return
