Just installed Peter's Date Package at www.PeterBlum.com and have been enjoying working with all the gadgets he has obviuosly spent so much time improving. Great job Peter! The price is definitely right, especially considering how much thought he put into the accompanying documentation. I built some of my own date controls similar to these, but I canned 'em for his package [after arguing with my pride].
A slight bug (may be something I haven't done right since I am still new to them) is in Firefox where the PopUpCalendar appears at the top of the view port. I am floating some divs since I am doing CSS layout (table-less) so I am wondering if that is the issue or if his script isn't finding the x.y position correctly. Haven't had time to dig too much deeper yet and it only happens in FF.
His VAM also looks awesome...can't wait to use those too.
