A pop-up window works fine & is the right size in IE, but in my Firefox it appears full-screen in a new tab, and I can't see what's up. Page is http://www.mexbro.dsl.pipex.com/webtools.htm#Java and it's the "mouse" link. code used: function openWindow(url) {popupWin = window.open(url,'remote','location=no,scrollbars=no, height=200,width=250, screenX=200,screenY=200,left=200,top=200')} <p>Or you can pop up a little box to expand on highlighted text if clicked with the <a href="javascriptpenWindow('mouse.htm');agon1();" title="Click here!">mouse.</a></p> (The agon1 function refreshes an animated gif on the page that stops working when a link is clicked).
Disabled Tab Browser Extensions (known buggy with FF, but been ok for me so far), now pop-ups work OK. Poo.
