Description

[Phil Smith]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0

On Win2K SP2/3, using either NS 7.0 or Mozilla 1.3a, it is necessary to close
the browser and restart it to pick up changes to screen resolution.  IE 5 & 6
pick up the changes.  To recreate, load the following HTML code, then go to
display properties and change the resolution, and either reload the page or
click on the button to see the previous rather than current screen resolution.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"

<head>
<title> Dynamic resolution change bug </title>
<script>
function get_res()
{
  alert( "screen.width=" + screen.width + "\nscreen.height=" + screen.height );
}
</script>
</head>
<body onload="get_res()">
<h1>Now change the screen resolution in Control Panel display properties.</h1>
<input type="button" onclick="get_res()" value="Recheck screen resolution">
</body>
</html>



Reproducible: Always

Steps to Reproduce:
1.with resolution = 800x600, load the page above
2.go to control panel, display properties, settings, change to 1024x768
3.reload page

Actual Results:  
reports 800x600 resolution (probably read when browser initialized)

Expected Results:  
report current 1024x768 resolution.

Works correctly on IE 5/6
