The application is for creating cheques via the web. One user creates it and then two other and different users have to approve it.

A list of cheques to approve is displayed with a APPROVE button for each Cheque.

When the first user clicks on APPROVE, the application is launched and his user name is enter in the record as a first approval and the list is diplayed again showing all the other cheques still to be approved (but not the one that was just approved). Right then. At that moment when the cheque he just approved is not in the list, if the user refreshes the page (F5 or Refresh from browser menu) his name is added as a second approval.

this and some other similar problems are why I want to prevent refreshing the page.

Any ideas ?
