It isn't the website I'm testing but it has a dropdown that demonstrates the issue I'm having. The issue seems to disappear if I change InvokeSelectionChanged to False but I'm sure you can see how that could be a problem with some tests.

Has anyone else had a similar issue?

Hello Erick,

I am sorry to hear you're running into this problem. The issue is already fixed for IE9 and the fix is included in our latest internal build 2012.2.1527. You can download it from your Telerik.com account here: Public URL. I have also recorded this short video to demonstrate how it works with the latest build.

Unfortunately the problem still occurs in older versions of Internet Explorer(IE8 and older). The bug is logged here: Public URL. We expect a final fix for this to be included in our next official 2013 R1 release.

Regards,
Plamen
