Thank you all for your suggestions.
Since this is a Windows Desktop gadget, I am working on the IE7 engine and it does not support the CSS property. Since these are buttons that have done their work as soon as they are pressed, there is no need to keep them in focus. I found that adding:
document.getElementById(theButton).blur();
for javascript, when you select a button, it clears the blue highlight.
There is a similar issue with A tags addressed with jquery: IE7: 0 schema not working
