Try fixing the HTML errors on your web page to see if this helps with your first and second problems.
Certain browsers may be more tolerant towards errors than others and this can result in inconsistent behavior across different browsers.
You can check the code on your web page with the W3C Markup Validation Service and then fix the errors reported.
Many of the errors on your web page may seem to be trivial and not directly related to the problems you report but there are a few stray tags on your page resulting in elements which should be closed which are not (and vice versa).
The <div id="juicebox-container"> seems to be caught up in the mix.

With regard to your third issue, when enableDirectLinks="TRUE" (which your gallery uses), each image in the gallery is given a unique URL and clicking the Back Button in a browser will step back through these URLs. This is normal and to be expected.
If you do not want this to happen, then set enableDirectLinks="FALSE" (in JuiceboxBuilder-Pro's 'Customize -> General' section) instead.

Okay... I created a new bare bones test form and ran it through the validation and it passed.  The content has the same issue on a Surface device and the page it locked except for the component.

The only way the page moves is to use the component and try to force the page up.  Using the white space does nothing.

Let me know what you think might help.

I tried it but no luck either.  The image swipe works which must be what is mucking up the page portion.  Hopefully they will have a solution.  Will you update the issue when you hear back?  Love the component but this will be a show stopper I have these surfaces deployed all over the place.

Thanks

Checking up on this to see if you received any feedback on possible work around regarding the issue with the Surface browser.  The screen locking makes a website unusable with this device and looking through your blog I see you have tested it on the Surface Pro which is what I am using so perhaps there is a fix or trick to work around it.

Fully Windows 8 Compatible

Windows 8 touchscreen devices such as the Surface Pro are fast growing in popularity. These devices hold a special challenge for web gallery design since they handle keyboard, mouse and touchscreen input. The Juicebox UI has been tweaked to handle this in a graceful manner.

Hopefully you can escalate this so I can get this working.  I do like your product but it needs to work on a Surface.

Please try the following.

Open the 'jbcore/classic/theme.css' file in a plain text editor and change lines 945-947 from:

body, html {
    -ms-touch-action: none;
}

... to:

.juicebox-gallery {
    -ms-touch-action: none;
}

Hopefully this will fix the problem.

Please note that the line numbers above refer to the current version of Juicebox-Pro (v1.4.3.2).
