There was a bug in 1.77.1: the new layout uses ez.css and it changes the z-index of the content. As a result the date/datetime/time popup appear under the windows.
I have not fixed this but please check it under IE since I did not get a chance to try that. z-index in IE behaves funny. Massimo -- Subscription settings: http://groups.google.com/group/web2py/subscribe?hl=en
