Rail 3 APP doesn't start

Hello @all!

I've created a new Rails 3.0.0 application using ruby 1.8.7 and MySQL.
In the log file I can see that the server receives the request from the
browser, but nothing happens afterwards:

Started GET "/products" for 127.0.0.1 at Mon Nov 01 16:30:23 +0100 2010

Old versions using Rails 2.3.* are still running fine.
Note I'm running on Windows 7 but I can also reproduce the same in a VM
using Windows XP.

Dows anyone have an idea?

Best regards
Marc
