    I have a Dot Net 4.0 Web app using Telerik controls.  

    It appears that my application will run fine if IE10 is in Compatibility Mode.

    It will not function normally if Compatibility mode is off.  

    I'm not sure if this is even an issue (for my company) but I'd be interested in hearing if there is any fix for this.

    Hello,

    We are aware of an IIS known issue for IE10 that might be related to the unwanted behavior you are experiencing on your site. There is a patch provided by Microsoft that is necessary to be applied to the server to solve it.

    For .NET 4.0 check this one: http://support.microsoft.com/kb/2600088
    For .NET 2.0:
    http://support.microsoft.com/kb/2600100 for Win7 SP1/Windows Server 2008 R2 SP1, Windows Vista/Server 2008, Windows XP/Server 2003
    http://support.microsoft.com/kb/2608565 for Win7/Windows Server 2008 R2 RTM

    You could find more information at various places on the internet like:

    If the listed approach doesn't help you to resolve the problem I would advise you to try to isolate the issue in a simple, fully runnable project and send it back so that we will be able to reproduce and examine it locally.
