hi, had the problem in the RC4, thought maybe update will fix it, but still doesnt work:
in registration form the calendar is shown correctly when clicking on a date field...
later in profile editmode the date fields aren't shown, and the user is unable to change date fields...the only thing is shown is the description ("birth date" for example) and the icons which say "shown on profile" and so on
tried both types of calender, no one works...
