menu buttons spacing FF Vs IE

[Purple Edge]

The vertical menu buttons are space further apart in FF than in IE - is there an easy way to prevent this from happening?

Can not reproduce this. Please provide a link to a sample page. Thanks!

I had some css in another file that was interfering, possible a table padding since it only affected the buttons in the table?

Please get rid of the table and use rollovers on the topmost ul/li.
