Some time ago Microsoft released Internet Explorer 11 and some of the users of a web applications I am working on, reported that they were not able to use the web application, they clicked some buttons and nothing happend.
This problem with a recommended solution is explained here by Mr. Hanselman.
In our case we just added a browser definition file to fix the problem. We know this is not the better solution, but we are about migrating to ASp.NET 4.5 that has a built-in fix for this issue.
It is incredible that the same issue happened when IE10 was released.
