[Plugin: WPtouch] Login option bugs!

Hi,

I have enabled the option to restrict comments to logged in users only.
However, since I have enabled this, the login option on the mobile site has broken. It allows a user to login (no option to register), and when a user is logged in, it show the link to register under “My Account”.

Why would a user need to register when the are already logged in?

I want people to be able to register on the site, using the mobile page, but not when they are already logged in!

Is there a way to fix this, or to disable to login option when login is required? I dont want to resort to hacking the plugin!
