Browser related style effect help

[ineuw]

In Firefox 2.0, I successfully changed the border effect of the standard Select box from sunken to a flat image, using the following CSS:

select.fonts { border: 1px solid #acacac;}

This works fine in Firefox, but in IE6, only the bottom border changed to the desired style. The other three sides remained sunken. What am I doing wrong?

Thanks in advance,
