Telerik RadMenu seems not supported in IE 10, we have telerik dll version 2010.3.1317.20 We have submenus which are not getting open when hover over the menus. Even main menus not getting open automatically when hover, it needs to keep on moving the cursor on the menu, then only it gets open automatically. This issue occure only in IE 10. It works correctly on all the other versions of browser. Here is a link to replicate the issue when open in IE 10 http://www.exair.com On the top nav menu bar, go to "Buy Now" menu, it has other sun menus, which are not open at all. Please let me know how do I resolve this issue.
