I'm sorry to hear that you are having trouble with Juicebox-Pro.
Hopefully my notes below will help.
Thank you for providing the URL to your gallery's web page via email.
I'm not sure what is causing your problem but here are a few things to check and try:
(1) First of all, try clearing your browser's cache before reloading your gallery's web page to see if this helps.
(2) I notice that your gallery's 'jbcore' JavaScript and CSS files ('juicebox.js' and 'theme.css') have been modified (comments removed and minimized). Try reinstating all 'jbcore' files and leave them exactly as they are (without modification) to see if this makes a difference. (If the files are being modified my a third-party module, then try temporarily disabling it.)
(3) As the comments have been removed from the 'jbcore' files, I cannot tell at a glance which version of Juicebox-Pro you are using. Please make sure that you are using the latest version (v1.5.1). If necessary, instructions for upgrading can be found here.
(4) Try setting expandInNewPage="TRUE" (to expand the gallery from the Splash Page on a new web page of its own rather than on top of the embedding page).
(5) Try fixing the HTML errors on your web page. You can validate the code on your web page with the W3C Markup Validation Service and then fix the errors reported. I realise that this might be quite difficult in a Drupal environment where the code is generated automatically (by themes and modules) but there are many errors on your web page (including duplicate ids and stray end tags) and this may be causing your problem. (Some browsers may be more tolerant towards HTML errors than others.) Once the code on your web page validates correctly, your web page should be rendered with greater consistency and predictability across different browsers. (Suggestion #4 above might avoid the problem by expanding the gallery on a new web page of its own away from the embedding page containing the HTML errors.)
(6) I notice that you use the Drupal module which is an unofficial plugin (not written by ourselves). As such, if you find that none of the suggestions above help, you might like to post in the Drupal forum where the author of the module might have heard of your problem before and be able to offer help.
Incidentally, please note that the UC Web Browser is an unsupported browser (Juicebox-Pro is not tested on the UC Web Browser) but Chrome is supported and Juicebox-Pro should (under normal circumstances) work fine in Chrome.
I hope that these notes help (or at least point you in the right direction).
