When cool design goes crazy

Squarespace (www.squarespace.com) is working for me as a web design and hosting platform. Above all, it keeps the design of www.financiery.com good by the intelligent limitation of options and setting of defaults.

But sometimes its own design beggars belief. It's all sleek and either black or white, and with skinny little scrollbars without a border. All very current and flat.

Here's the challenge. Can you see the scrollbar bottom right in the image, next to Invoice Financing? Can you see the thumbtrack on the scrollbar? It is there, I assure you.

Why is this? Would the community really melt down if a bit of ease-of-use over design cool were allowed?
