[Plugin: WordPress Mobile Pack] Desktop Link In MultiSite Not Working

I am using WP 3.2.1, multisite, with sub directories (not domains – so domain.com/site1).

The plugin seems to work fine until I try enabling the desktop link in the footer. Rather than pointing back to the full domain, it only gets the site folder value.

So it will point to http://site1/?wpmp_switcher=desktop

How can I get it to point to http://domain.com/site1/?wpmp_switcher
