Yaron is perfectly right. The reason for not updating the inline queries is MediaWiki's cache, made of various special components for the purpose of improving performance. If you do not want a cache but prefer continuous recomputation, you can switch it off as suggested by Yaron. This is OK on small sites, but not on large sites (which is why it is not the default in MediaWiki).
The "refresh" tab is hidden from normal users since it makes the interface more complicated, but the action of clearing a page's cache is available even to anonymous users (there just is no dedicated tab for this). Some other ways of updating your cache are: * Make a cron job on your server that executes "touch LocalSettings.php" every day or so. This will cause the cache to be refreshed regularly, without breaking it completely. * Hide the refresh tab but provide an inline link to "update this query" on relevant pages. This can be done by a simple template that does not need parameters, similar to http://ontoworld.org/wiki/Template:Update. Unfortunatelly, it is not easy to automatically find out which pages contain queries that need to be refreshed after some change, which is why this is not done automatically.
