If AJAX-ZOOM "responsive" parent container is resized with javascript by e.g. click on a button, then you might want to call jQuery.fn.axZm.resizeStart(3000); when it starts resizing and jQuery.fn.axZm.resizeStart(1); when it definitely ends. No need to do this if your responsive layout is resized by window resize or orinetation change events, AJAX-ZOOM will do it instantly then.

Also please note that among many, many other settings and design restyles you can also this black toolbar under the player and a different one if you want. Please also take a look at example33_responsive.php with hotspots made with hotspots configurator (example33.php).
