Scheduled published version not updating until page is accessed in edit mode

Vote:
 
I'm using scheduled publishing for making changes to a version of an already published page. Eventhough passing the scheduled publishing date the changed version does not appear when visiting the page externally. But, as soon as the page is viewed through edit mode the changes are made visible, inside edit mode aswell as externally. Tried using editor user account and admin account - same results. Using EPiServer version 4.51. Any ideas?
