Thanks, Rene
That topic applies to options for the JQuery datepicker script, which, while interesting, don't really apply to the Base theme implementation. Somewhere in the theme CSS there is a property that hides the next month and last month buttons until the user hovers over them. I am sure the problem is in the original bootstrap code but I just can't find it. The problem can be seen in any example app that uses the datepicker and the base theme.
Bruce, my snarky reference was about the end user experience. Relying on users finding the functionality by accident doesn't seem the best design strategy from what is in other ways a very attractive and functional theme. I have had three client organizations spontaneously mention the 'missing' next / previous month buttons in the few weeks I have been using the Base theme for my Web Server app, so I know it is noticed by users.
Thanks.
