Checkout issue - Continue button not working

[OC2PS]

I have run into this weird issue. Every day, I receive 2-3 calls from customers who face this problem.

When they click "Checkout" and log in, then after selecting the address in Billing Details, clicking on CONTINUE button does not work.

What's particularly challenging is that this problem is not consistent or predictable. It is so notoriously difficult to replicate that for the first few weeks, I dismissed the customer reports as "stupid users" and tried to tell them to use Tab and Enter or Refresh page, etc.

On my 4 machines, 99.99% times, the checkout process works fine. But I have been able to replicate the issue in both Firefox and Chrome. Unfortunately, I can't help with specific factors that help replicate the issue, except for using lots of different machines, and to try checking out lots of times.

Now that I know the problem is real and that it's turning away several customers every day, I would greatly appreciate a fix.

Sorry about that, but at one point you said you don't have time to check the forums...so I figured it better to post in forums first for others and then here for you...
