I was able to replicate on the said issue. This can be a script issue, can you please try to embed your form using iFrame method instead: http://www.jotform.com/help/148-Getting-the-Form-iFrame-Code
Please update us if this works for you.
It appears that you have replaced the script with the form's full source instead of the iFrame version. However, my tests at Browserstack indicate that that works as well as the iFrame in this case. The only drawback with using the full source is that whenever any change is made to the form, you will need to re-embed the code into the page. There's no such issue when using the iFrame.
Should you experience any further issues, please let us know.
