back-to-top nav prevents clicking checkout button

[drbyte]

Perfect storm:
When the browser's exact window size (including shipping/payment/comment/coupon options that affect vertical positioning) positions the "Continue" button exactly in the lower right corner where the back-to-top nav hotspot exists, it's hard to click the "Continue" button.

Curiously, the back-to-top nav hotspot is "invisible" when no scroll is necessary, but it is still clickable at all times. And that's what interferes with clicking checkout buttons.

Scrolling the page or finding the edge of the Checkout button allows one to click it to proceed.

Perhaps just don't create that back-to-top link during checkout?

... or, as an alternate possibility, center the back-to-top icon on the bottom of the screen?

I'm not sure it's a showstopper issue.

If the hidden element were to become unhidden-upon-hover then perhaps at least the end-user would realize there's a clash and just scroll their screen accordingly.
