rich,
i think it happened when i hit the back key to go back to the list of forum subjects, then when i'd click another forum forward, it would post again. since that fiasco i've just closed the window and then opened another to look at another forum. i try to avoid the back button if i've written anything. i truly pressed the enter key only once. and i'm on cable broadband. we'll see if closing the window and starting over with a new window helps.
