I'm working with UI for ASP.Net 2015.3 and I'm starting to get a strange error when I'm trying to do an ajax post in IE 10/11 -
Unhandled exception at line 563, column 32 in http://localhost:9090/WebUI/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=3.5.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:f425c57c-3f06-4ae5-9b9a-1c136e57ba79:ea597d4b:b25378d2;Telerik.Web.UI,+Version=2015.3.1111.35,+Culture=neutral,+PublicKeyToken=121fae78165ba3d4:en-US:148acb90-275a-4dd3-bcec-73473d72fc70:16e4e7cd:4877f69a:86526ba7:f7645509:ed16cbdc:88144a7a:24ee1bba:c128760b:1e771326:f46195d3:2003d0b8:aa288e2d:258f1c72:a675b4ab:bfc858fd:58366029
0x800a138f - JavaScript runtime error: Unable to get property '_events' of undefined or null reference
I've seen other posts with errors like this one - the suggestion is usually upgrade to latest version, but 2015.3 seems pretty new.
Trying to run this page in an ie emulation mode for an earlier version of ie does not resolve the problem.
Any ideas why this would start happening?

With the provided information only it will be difficult to pinpoint any probable cause of the error, but you If RadCompression is enabled in the web.config file, try to remove it and see if it will make any difference.
If the issue persists, please elaborate on your exact scenario and what controls you are using on the page.
