We encountered following problems with the version 2012.1.215.35
1. Enter button stopped working for all the pages, if focus is on any of the other controls on the page. For example , in login page, the default onload cursor was on username field, if we just pressed entered, it did not work, if we clicked on any other point on the page and clicked enter, it worked as expected.
2. RadDatePicker control - behavior changed for some pages- if the date field is clicked, in first click, it was highlighting the date and showed the calendar control in second click.
After downloading the version 2011.3.1305.35, these problems were gone.
Thanks
