Like everyone else, I seem to be beating my head against the wall to make the modal popup extender work in a module in a way that doesn't require changing the doc type.

However, I don't seem to have any problem positioning the popup and in fact, the entire thing works great for me on Firefox.  I simply set the X and Y properities on the control before calling Show...  My problem is with the background (only in IE).  When I display the popup, the area within the module extends to some ungodly size and doesn't display the background coloring and obviously, nothing is disabled.  The popup does display as expected and it displays in the location I set the x and y properties to...  Adding the xml file for the skin doesn't seem to make a difference (IE still doesn't work and FF does). 

What am I missing?  Every thread I've found seems to deal with positioning of popup, not problems with the background....

Also, beyond my control is the fact that I'm using dnn 4.5.1 as the dev platform...

Thanks for any thoughts!
