Does it happen for firefox too?
I haven't tested in FireFox. But it doesn't happen in Chrome. It happens in IE 9 only.
I dont have your problem with IE9. could you post a example code ?
Did you find any solution for this problem? I might have same problem, but I'm not able to reproduce it reliably. It might be connected to some network issues.
