I tried and quite succeeded with v1.0.0. I have yet to succeed with v1.5.0.
A slight problem I encountered with IE6 however is with the field for selection
of single names. It seems that the borders of the Team Leader field become
rendered like the old input fields of earlier IE's. This always happens here
after the color changes after the entry is shown in the field.
I'm still tweaking with v1.5.0 that's why I can't take a closer look. I think
the tweak should go somewhere after (or within) the "new
Effect.SlideDown('NamesPicker')" line in js/NamesPicker.js although I'm not
sure what to do.
