I don't know if we mean the same but I can't use OWB for Paypal. Because when I enter a mail adress it asks me if this is a private or business payment. I slect private payment and after that it tries to load something that never finishes. I can scroll down the page (scroolbar on the right) but the visible content stays the same. It never finishes. After some time Paypal logs me out and that's it. So I can't do any payments with Paypal anymore.
