[Plugin: W3 Total Cache] Rejected User Agent problem

Hi

I am having a problem using W3 Total cache with the WP Touch Pro mobile theme.

I followed the instructions for getting the two to work together and added the various user agents into the Rejected User Agents field on the page cache, minify and cdn settings pages.

I have cleared all caches (both in W3 Total Cache and locally on the browser), yet it appears to be ignoring the settings and still using W3 Total cache.

I have tested this with an iPhone, and with Firefox on a desktop using a plugin to change the user agent to the iphone user agent. If I view the source on the latter (which does bring up the mobile version of the site) it includes the following at the bottom, which suggests W3 Total Cache is still being used. Any ideas?

The settings are still showing when I go back in to edit them again, so they are clearly being stored somewhere, but apparently not used.

(FWIW the main issue this is causing me is that none of the drop down menus are working when viewed in the mobile theme.)
