Responsive dropdown menu bug

It's ok with me , you need to click on it. What browser do you use?

On my S3 I use the stock browser named Internet (Version 4.1.2-I9305XXBLL5)
If I click on the menu button the items are visible for 0.1 secs and disappear

Now I tested it on a Galaxy S2 with the stock browser and with Firefox on my S3, same problem. Navigation does not work. Maybe it's a problem with android browser?
I added two screenshots, one with my page and the other one is the bug on your demo ( demo.hotjoomlatemplates.com/one_page/ ). As you can see the menu does not work properly. The shots are from my Galaxy S3 on Firefox browser. Responsive menu is enabled in template options.

try this open template_css.php

select.tinynav {...
....
-webkit-appearance: button;
-moz-appearance: button;

remove this two properties and check what you get then

I tried it out, but with no success at all (see Screenshot). The menu still behaves like before, only the button is gone. Is there a possibility to completely disable the menu in the responsive view (when the responsive dropdown gets active) ?
Hope you can help me out with this.

Thx, C

So when you tap it nothing happens?
