Links to Forum topics being rewritten wrong (Latest Forum Topic block)

I had a fair few issues with setting the path correctly. I think this is compounded by the fact i'm using Windows in a development environment, but will likely be forced to use Windows for live too.

It's installed at:
C:\wamp\www\drupal6\phpbb3\

The only way I can get it to work is by setting the path in phpBB forum settings to ./phpbb3. Which works fine for pretty much everything apart from the Latest Forum Topic block. Some of the links are being rewritten as ./phpbb3/forumtopic.php.. When it should be /phpbbforum/forumtopic.php.

I fixed the topic link itself by changing the line in phpbb_api_recent:
$view_topic_url = append_sid("{$phpbb_root_path}viewtopic.$phpEx", $view_topic_url_params);
to
$view_topic_url = append_sid("{$phpbb_url}viewtopic.$phpEx", $view_topic_url_params);

The author link I can't work out how to fix, as it's being generated by a phpBB function.

Thanks for the great module by the way, I can tell from spending the evening digging through the code how much work has gone into this!
