javascript exception thrown only after load() and only in IE

javascript exception thrown only after load() and only in IE

I am using a in-browser pop-up (hidden div) with a full screen overlay set to 50% transparency to make the pop-up the center of focus. 

I utilize show() and hide() with no problems as long as the content of the pop-up div is hard coded in the HTML. However I need to have the content of the pop-up div be generated via a .load() or .ajax() (I have used both the problem is the same with each). 

The content loads no problem and the pop-up div is visible.  However, when you click anywhere on the screen the following exception is thrown. 

  Unhandled exception at line 626, column 17 in script block

  0x800a138f - JavaScript runtime error: Unable to get property 'style' of undefined or null reference.

This exception only occurs in IE (I have tried in both IE10 and IE11). In Chrome there is no problem. 

More over when attempting to figure this out I commented out all jquery click events. I then click the screen (it does not effect the result if I click in the open div or the background overlay) and the same exception is thrown. I does not seem like an event should even be triggered.

Any help with this would be greatly appreciated. I have been Goggling  this and banging my head against the wall for two days.

Thanks
