Register & Cancel

Sorry, my German isn't good enough to read many of the posts.

Thanks for the Plugin, looks very promising and I love the admin protection but...

On testing I find that during registration the register button doesn't always work and the cancel button seems to fail more often. When this occurs the user has no way out of the registration form other than to load another menu item.

It is the same when the registration form is called from a login menu link or from Kunena.

Test environment -- local WAMP server.

Where should I start looking for the issue?
