It looks that user is not only able to browse within disabled days and months, but also selcet those days..

Example:
If I will change month / year to let’s say next one, it will automatically display in select box first available date in that month in my input box, even if I didn’t selected that date. It causes a problem, especially if you will disable some days – it will allow to user select those disabled days using this “hack’. Is there any way how to change this behaviour?

Thanks for help!
