Working (rather) in Preview Mode but no page display

I have followed all troubleshooting advice that Karen posted on the project page, and am running the latest dev versions of Calendar, CCK, Date and Views. (6.x-2.x-dev) I have cleared the Views cache, the Theme registry, and truncated every table that starts with "cache". This is a D6.10 site and I just "upgraded" from the stable releases of these modules in order to get Repeating Dates working (they weren't working before).

I have a content type called "Event" that uses a cck datetime field, and the widget type is Select List. Default value = now. Optional "To date". Granularity = sec. I also have a nearly identical content type called "Repeating Event" which has no "To date" and granularity = day.

In the "Event Calendar" view that came with the Calendar module, the argument is set to "Provide default argument" type = Current Date and Granularity = month.

The following behaviour occurs in Preview mode:
- The Defaults display shows the table header row only; does not include my test event
- The Page display shows the table header row only; does not include my test event
- The Block display shows the table header row only; does not include my test event
- The Year View shows the Month View (!) except Sundays are normal cells with blue dates
- The Month View shows the Month View and Sundays are collapsed-width cells with red dates
- The Day View does what the Year View does.
- The Week View does what the Year View does.
- The Block View does what the Year View does.
- The Upcoming View worked properly, except it was looking for Updated Date >= now instead of my CCK datafield >= now. That seems wrong, eh?

The /calendar page displays a 403 error. If I assign the date arguments manually to the URL (i.e., "calendar/2009-04"), only the table header row shows up. No events are displayed, in fact no grid is displayed at all. I can move from month to month using the << and >> links but still only the table header row is displayed. Screenshot attached.

The rows and cells below the header row (i.e., the day cells with the content in them) simply do not exist - i.e., they are not in the HTML of the page, they are not merely obscured or hidden via CSS. They only exist in Preview mode.

However, if I run the same query in PHPMyAdmin, I get my test event, so I know it *should* be there. Any clue what is happening?

Here is the export of the view:

$view = new view;
$view->name = 'event_calendar';
$view->description = 'A multi-dimensional calendar view with back/next navigation.';
$view->tag = 'Event Calendar';
$view->view_php = '';

$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
