Non-usable page appears for mobile.zoho.com site

I've got a Motorola Q phone running Windows Mobile 5, and when I use Pocket Internet Explorer to visit the mobile.zoho.com site, all I see is a blank page with a "home" link in the top left corner, and a "logout" in the top right (note, I didn't even login yet). In the middle is the "Zoho Writer" logo, and a blank page below.

I don't seem to have a way to login, and thus can't view my online doc files. Am I doing something wrong, or is there an issue with using mobile.zoho.com with Pocket Internet Explorer?

Thanks.

Dave
