Not pretty but it works....
In /customer/home.tpl look for the line
Code:
{include file="location.tpl"}
and replace with
Code:
{if $main eq "catalog" and $current_category.category eq ""}
{else}
{include file="location.tpl"}
{/if}
This will also give you the option of inserting something else right before the {else} if you wanted to include something besides the location.tpl rather than just not displaying it at all.
