Check out as Guest problem

[david.kwock]

Hello all 

When I fill in the billing form to check out as guest, I accidentally click on the Register button without filling in any username and password, so VM2 warns me that I need to fill in the registration form.
But I still want to check out guest so I just proceed the check out as guest. However, VM2 still wants me to fill in the registration form...then I should cancel the form and come back again..

Is there any method to prevent this problem???

Thank you for your help in advance !!!
