Hi Chat,
I am sorry to say but the information provided is insufficient for us to determine the root cause of the problem. There are a number of reasons which may cause this behavior and in order to resolve the issue I would like to ask you to provide us with a sample project which replicates it. In most of the cases the problem is caused by an unregistered handler in the web.config file. Could you ensure that this is not the case? Please give the approaches listed in
this forum post a try and test whether some of them help to resolve the problem. Additionally if the issue is reproducible only in IE10 you can install the .NET fix mentioned in
this sticky thread.
Regards,
Angel Petrov
