I have implemented a CRUD schedule in ASP.MVC with all the functionality I need. It works fine, except for the following issue in the popup that allows to Add, Edit or Delete an appointment (see attached image):
The first time my view page is loaded and I open the popup to add a new appointment everything is fine. However, the second time and the consecutive times I open the popup for any operation, the input boxes, the text area, and the datepickers are somehow blocked (they are not disabled, but do not respond to mouse or keyboard events, getting the focus or displaying the calendars), and I can not insert or change their values. I reviewed the HTML with firebug and was not able to find any attribute or class that could be causing such effect. All other controls are enabled and work as intended.
I will appreciate any help with this issue. Thank you in advance.
