on pp_confirm.php try adding the invoice id after the taxtotal al ine 138, so this:

$WA_PP_ECO_Do_optional[0][$nextIndex] = "TaxTotal";
  $WA_PP_ECO_Do_optional[1][$nextIndex] = "".$eCartSMC->GetTax()  ."";
  $nextIndex = count($WA_PP_ECO_Do_optional[0]);

becomes:

$WA_PP_ECO_Do_optional[0][$nextIndex] = "TaxTotal";
  $WA_PP_ECO_Do_optional[1][$nextIndex] = "".$eCartSMC->GetTax()  ."";
  $nextIndex = count($WA_PP_ECO_Do_optional[0]);
  $WA_PP_ECO_Do_optional[0][$nextIndex] = "InvoiceID";
  $WA_PP_ECO_Do_optional[1][$nextIndex] = "".session_id()  ."";
  $nextIndex = count($WA_PP_ECO_Do_optional[0]);

That should prevent duplicate transactions during the same session.

Did this help? Tips are appreciated...
