Has anyone had any issues with using the Select2 jQuery plugin in a DNN6 instance, specifically under IE11? 

I am working on a DNN6 website and the problem that I am having is that anytime that a key is pressed in the Select2 input / textbox field, it immediately loses keyboard focus, limiting the use of the plugin.

I have tried this in different environments:  A plain old fashioned no frills ASP.NET web application and also a DNN 7 website, and in both cases the plugin works perfectly.  

The dropdownlist control that I have wired up to use the plugin only has Select2 set the width in Javascript code on load.
