Date is removed in Event module when updating

Hi, please forgive me if this is a superfluous bug report but I have only been using Drupal for about a week now ( and I think it's great ).

When you create a new Event everything is cool, it appears on the calendar and in the Events page. However when you go to administer the event and Submit your changes the date of the event is cleared from the database, this means that once an event is created you cannot change anything in it without destroying the time it will take place, a bit annoying !

If you turn on the SQL you can see that the module is simply submitting an empty string to the database when you hit Submit, I have looked at the event.module and it seems to be getting the start time from the node table, exactly how this is working I am not yet sure.

Please slap me down if this is fixed somewhere or blatantly obvious but I have looked on the forums / bug reports and cannot find anything similar. Also I notice that there have been bugs raised about the event module creating errors in the search with a missing column b.abstract which had been fixed but I have noticed that I am getting errors in with the event in the search module on a column which doesn't exist b.detail - it doesn't exist but again I can't see exactly where the search.module is picking this up from yet. Need more time to look around this excellent system.

Thanks.
