Have you used your browser's debugger to look for errors?

Right-click on the webpage and choose "inspect element", which will split yur borwaser window. You can use the various panes in there to check for javasvcript errors or interact with the JS consoke

There is something different about your pc or the browser you are using so I don't know what you want us to do. Use the developer tools in your browser to see what might be happening.
