Hi george,
Welcome to asp.net forum.
I review the links above, it seems that this issue is related to document compatibility.
<head>
<!-- Use Internet Explorer 9 Standards mode -->
<meta http-equiv="x-ua-compatible" content="IE=9">
</head>
We use this meta tag to define document compatibility in Internet Explorer. In this situation, <META content=IE=9 http-equiv=X-UA-Compatible>, it means that IE 10 throw new features comparing to IE 9. In other word, IE 10 will act as IE
9.
In addition, it doesn't work on your side, you could also consider sunbmitting this to Microsoft Connect site, Microsoft
engineers will reproduce this issue according to the proof you provide.
If you have any concern, please let me know.
Regards
Angie
