First of all, Pickadate is just awesome (well built, great api, highly extensible, a pleasure to work with).

Thanks for it, I just discoverd it and I feel that it will become my only reference for date/time picker.

I did find a small issue that I think can be easily fixed:

Steps to reproduce:

1. Go on http://amsul.ca/pickadate.js/index.htm
2. Click on the first picker input
3. Click on a date to choose one (picker should close itself)
4. Click out of browser window
5. Click in the browser window (anywhere in the page)
6. BUG: The picker opens without the user clicking on it

Tested on Google Chrome Version 27.0.1453.110

I hope you have enough infos to fix, keep on the great work!
