Roel - I just installed 4.7.3 to a db that I deleted everything, and did a clean install. When I click on login, the icon depresses, but nothing happens. Same thing with trying to change months. I click on the arrow, nothing. The only thing that works is the calendar icon. It opens, and I can scroll through the dates, but the calendar does not change.
I am running 4.5.2M on another site and it works fine.
Any ideas?
Bob
