Coming Soon page shows header and footer

[DaveD]

Hello there,

I have played around a bit under the themes editor - options - passwords in order to set a coming soon page. I was trying out different things. Before I started it was more or less a blank page with the information, coming soon. Now still the same but it shows also the header and footer of my store (which is currently still under construction).

If I remove the menu/ header and footer then it will disappear also from my draft-page.

Question: How can I edit the password-page without touching the "real" store? Do I have to create a copy of the store?
