I have updated a test program to last version 4.1.2 and now in IE11 when i click to filter a column it shows correctly the pop up to enter the values to compare. The problem is that Filter and Clear buttons doesn´t render properly. The down line of the buttons doesn´t appear. In previous version i did not have this problem.
I have other test in another program made with asp.net mvc and i dont have that problem. The one that fails is under asp.net webforms solution.
