jQuery Week Calendar overlapping problem

Question

Hi,

I'm developing an application with uses this calendar for resource reservation, but I have a problem when creating a new event.

I don't want events to overlap, so I set allow allowCalEventOverlap to false. However, it still overlaps in a transparent way. But the biggest problem is that I can't drag an event if there's another on the same day, even if their start and end dates don't overlap.

You can try this strange behavior in the 2nd demo: http://robmonie.github.com/jquery-week-calendar/weekcalendar_demo_2.html

Any help on how to fix or understand it will be very appreciated.

Regards,
