In discussing this more on list we have now decided that the proper way to address this, at this point, is to just simply add the fl-focus class into the demo.
The original fix which added the blue outline to the dialog's controls does NOT work for IE6 and IE7 on Win XP.

This actually turns out to be a bit larger than originally believed. In discussing this with James, Michelle, and Anastasia we decided that focus should be always added by the contrast themes. This means that they shouldn't rely on the fl-focus scoping.
Steps to reproduce
1) Open the "Full No Preview" version of UI Options from the UIO Demo
http://build.fluidproject.org/infusion/demos/uiOptions/html/uiOptions.html
2) Change the contrast theme to "White on Black" or "Yellow on Black" and save
3) Using the keyboard, place focus on the "Save and Apply", "Reset and Apply" or "Cancel" button. Notice that there is no visible focus styling
