Let me start by first saying, "Thank you!" The speed of the response and a code-level response at that is greatly appreciated. Let me know where you'd like me to post some positive feedback and I'll be happy to do so
Now, having said that... let me just state that I feel like a bit of an idiot right now. I became a victim of tunnel vision as I searched for possible solutions. I was trying to follow directions a bit too much instead of opening my own eyes. Right there in front of me was not just uddeim.css, but also uddeim-ie.css.
The whole time I was just needing to edit the IE version to get the solution I was seeking. I changed the background color there to "blue" as suggested, and had my fix.
I am loving the work that has been done with uddeim and am obviously impressed with the rapid support response. Thanks again!
