can't delete event category, wrong task date

can't delete event category, wrong task date

Dear VO programmers,
We have, two small problems.
first: is possible to add new event category in calendar, but can't delete them;
second: if in window "New Event", "created an associated task" box is checked, then after making this task, task date is different than event date, in our VO task date is set at 12/31/1969.

Thank you so much for fix problems by SS3.
regards radbis
