If you’d like to paste the ‘current’ query into the ‘alerts’ page you listed, I’ll take a look to see if something simple is amiss that is causing the query to be ignored.
When the mashup query is ‘current’, MapPress displays locations based on the posts in the WordPress global query object ($wp_query). Normally this is set to the posts you’re currently viewing.
If the Views plugin isn’t setting that global query properly, it won’t be possible to sync the map with the list of posts. You might try using the mashup POI list instead, which is always linked to the map.
