I have a little problem when edit calendar:

Release 5.0.11_GA_2695.RHEL5_64_20081117021643 CentOS5_64 NETWORK edition

-create a new user
-set only the calendar and preferences functions.
-create a new appointment.
-edit the appointment.

when i try to edit the appointment, nothing happens, don't update the info.

This happen in IE, Firefox and Seamonkey ( i try diferents to discard the browser problem.)

I search over the forums and the bugs but I don't found information about this problem.

Any Ideas...
