Message rules don’t allow me to specify a folder to move/copy in Windows 7

I successfully set up two message rules when I set up my new windows live mail.

However, any further attempts, even with the 'stop processing more' ticked, have resulted in my not being able to specify the destination folder.

The folders all come up, but when I highlight any folder, the "OK button" won't come up.

Thus, I cannot make any more message rules.
