this is getting confusing because of my double-posted question...

I assume there is a TARGET="_BLANK" reference somewhere that I'd like to eliminate, and hopefully not have to do so on each individual product page. You said you answered this, but I don't understand the answer (in either post...)
And why a question should only be posted in one thread

The already answered was in ref to the home page link

The href for the "webpage" link is designed for a link to a manufacturers page as a "product url" but it is in tpl_product_info_display.php and to remain dynamic will have to be some php
