I have an internal web application, that is IE specific, and uses a lot of IE specific modal boxes: (window.showModalDialog).
I recently received a request to remove the "flash" when navigating between pages of the site. To accomplish this, I just added a meta transition tag to my master page:
<meta http-equiv="Page-Enter" content="blendTrans(duration=0.0)" />
This works perfectly except for the modal boxes. When you launch a modal box, and then move it around, the web page behind it keeps a trail of the modal box instead of re-drawing the web page content. This prevents the user from moving the modal box to read anything that was behind it.
Is there a way to prevent the "flash" between pages in an IE specific site and have the site still work with modal boxes?
Please note, this is a large and complex site, so re-architecting it to not use modal boxes isn't an option.
This is an asp.net, c# web application, and all of my users are using IE 7 and IE 8 if it makes any difference.
-Edit-
To duplicate this, put the following into an html page, and open it in Internet Explorer:
<html>
<head>
<title>Test</title>
<meta content="blendTrans(duration=0.0)" http-equiv="Page-Exit">
</head>
<body>
<script language="javascript">
window.showModalDialog('modal.htm', window);
</script>
</body>
</html>
