Drupal 7 Draggable Views in different order when logged in
This can be resolved by following this link:- 
http://drupal.org/node/616658

Scroll to the bottom, and follow instructions in the last Post whereby you install the Rule module, create a rule to clear cache on sorting a View, you may have a problem where the option to create custom PHP is not in the drop down list, if so, this is resolved by enabling the 'PHP Filter' module.

All tested and works perfectly ! :)
