Turn off cache for specific items

Thanks — just sent you a PM.

Ok, the problem in your case seems to be browser level caching (although not sure), if you click CTRL-F5 to bypass browser cache the results appear immediately.

You could examine adding new feature to instruct browser not to cache page specific Content Types (and maybe also specific items)

You could use this J2.5 to add HTML headers for specific menu items, that will disable browser level caching:
extensions.joomla.org/extensions ... ards/12785

All right, thanks — I'll give it a go

Also try inserting this into the item.php of the item layout template file used for displaying your items:
