No it is unfortunatelly a problem with Goodreader and panoramas. There are 2 ways to deal with it.
1.Make a normal HTML page and use that as intro page, Then make a close button in the pano that links back to this page.
2. You can go to the iPad settings and in the Goodreader app settings set the option to on.

Unfortuantely you need to do this each time you have seen a pano.

However there are other apps much better for panos. They are hard to find but I found 2 which are very good.
I will soon make a review of them but the best one HTML Books is actually going to be updated with functions I have asked for.
I hope he soon makes the update.

Search for HTML Books in the store and for Sites2Go

Whoah I posted the answer to this ages ago!
As long as you don't disable the console log...
1. Swipe up bottom right
2. Tap once.
Goodreader menu comes up.

Sorry Sacha but those are always locked when I deliver to my clients.

Sure but I assume you only use goodreader yourself and can open the console with a hidden button when built for goodreader or if for a client you can overlay any popup with JavaScript to create the same spot for a touch.
