Editing the start date of reccuring events

I have problems with editing reccuring events.
Altering the start_date of an recurring event is not submitted when updating an recurring event so I can’t move the existing recurring event to another date.

The dhtmlxSchedulerConfiguratorLoad.php sends the wrong form data:
7_start_date:2011-10-03 13:30:00
even if set the start_date to 2011-09-03 13:30:00

Changing the start date of a single event works perfectly, but not for recurring events.
Is there any way to fix this problem?

I’m using the Event Calendar / Scheduler Plugin 2.3.1 and WP 3.2.1

Could you provide link to your scheduler page and ability to add/edit events?

For some reasons requests to your server take about 3-4 seconds.
You change recurrent event (create for example) and before it was saved you try to edit one event from created list of events. It’s incorrect logic for scheduler. Try to optimize your server configurations to make requests quicker.
