Wiki Widget and Widget Logic

This may fall outside of the realm of this plugin forum, and into the general Wordpress area...

I'm trying to set it up so that the Wiki Widget only appears on Wiki pages, and not on sidebars in the rest of the site. I've downloaded the Widget Logic plugin http://wordpress.org/extend/plugins/widget-logic/ and have put this string in the code area

is_user_logged_in() && is_page('support')

"support" is the root wiki in this case. This works to allow the widget to appear on the main wiki page (and private to users on the BP install), but the widget disappears on the subpages/subwikis. is_subpage doesn't seem to be a relevant function. Any ideas how I could get this sidebar widget to only appear on wiki pages?
