farsi-persian keyboard not working

Hi,

This plugin seems to be the most complete virtual keyboard for WordPress but unfortunately it does not work!
When I select full keyboard, it does not appear on the page at all. When I change it to widget, a button shows up on widget areas and when I press the button an empty pop-up box appears without any keyboard.

There is no settings on the panel to change the virtual keyboard settings. It only exists on pages and it is not clear where on the page the keyboard is suppose to be.
It would be much more useful if we could use a shortcode to place the keyboard wherever it is needed.

If you can fix these issues, this is the best of the kind.

Regards.
Nima
