Rebecca,
In the IdentifyWidget.mxml there is a glowFilter component that has its color defined by color="{getStyle('focusColor')}". If you change that to say color="0xff0000" or what ever color you wish. The issue is you are using a white theme for your viewer and the button use white as well to indicate the selected button. You can also adjust the glowFilter strength.

Hi Robert,
Apologies, I obviously forgot to set this to alert me when someone answered. This did the trick. Thanks again.
