Weirdness on Reload

[orion]

Hello, After I create a record in a DB, I come back to a list page, where I see the newly created data row on the list page. OK so far. If I press the browser's reload button the same row as the newly created one duplicates itself. Everytime I press the reload button, it keeps adding the identical data record in the DB. What gives? Please give me any clue. I really appreciate any idea in advance.   Simon,
