Hello (again ;) )
I've searched the forums and given the various suggestions I found a try to resolve this issue (space below the logo image and above the nav bar)

I tried removing the following line from my tpl_header
<br class="clearBoth" />
and that resulted in my nav bar migrating upward past the bottom edge of the logo image

I also tried adding a negative margin-top (in ems) to NavCatTabs and it looks good in Firefox, but the gap is still showing in IE.

IE is flummoxing me

Any suggestions?
