No Scrollbar when Multiple currencies are listed on Website

Hello ,

There are couple of issue with the plugin, please check.

1. If I list more than 30-40 currencies, I would expect a scroll bar to scroll down and select the desired currency.
2. Users are not able to checkout in INR. I have noticed the issue just for INR but it could be with other currencies as well.
For e.g. Indians customer are not able to checkout, same issue for other countries as well.
