SQL Dev 2.1 - Session browser Active SQL showing duplicate queries

Question

Haven't noticed this before in any other version but then hadn't realy been looking but when i use the session browser to check code running on the DB in the ACTIVE SQL tab i ocassionally see duplicate sql statments, which can be misleading, see below for an example.
SELECT SUM(AID.AMOUNT),
DECODE(APS.PAYMENT_STATUS_FLAG,'Y','Paid','P','Partially Paid','Not Paid')
FROM PO_LINE_LOCATIONS_ALL PLL,
PO_DISTRIBUTIONS_ALL PDA,
AP_INVOICE_DISTRIBUTIONS_ALL AID,
AP_INVOICES_ALL AIA,
AP_PAYMENT_SCHEDULES_ALL APS
WHERE PLL.PO_LINE_ID = :B1
AND PLL.LINE_LOCATION_ID = PDA.LINE_LOCATION_ID
AND PDA.PO_DISTRIBUTION_ID = AID.PO_DISTRIBUTION_ID
AND AIA.INVOICE_ID = AID.INVOICE_ID
AND APS.INVOICE_ID = AIA.INVOICE_ID
AND AIA.CANCELLED_BY IS NULL
GROUP BY DECODE(APS.PAYMENT_STATUS_FLAG,'Y','Paid','P','Partially Paid','Not Paid')
SELECT SUM(AID.AMOUNT),
DECODE(APS.PAYMENT_STATUS_FLAG,'Y','Paid','P','Partially Paid','Not Paid')
FROM PO_LINE_LOCATIONS_ALL PLL,
PO_DISTRIBUTIONS_ALL PDA,
AP_INVOICE_DISTRIBUTIONS_ALL AID,
AP_INVOICES_ALL AIA,
AP_PAYMENT_SCHEDULES_ALL APS
WHERE PLL.PO_LINE_ID = :B1
AND PLL.LINE_LOCATION_ID = PDA.LINE_LOCATION_ID
AND PDA.PO_DISTRIBUTION_ID = AID.PO_DISTRIBUTION_ID
AND AIA.INVOICE_ID = AID.INVOICE_ID
AND APS.INVOICE_ID = AIA.INVOICE_ID
AND AIA.CANCELLED_BY IS NULL
GROUP BY DECODE(APS.PAYMENT_STATUS_FLAG,'Y','Paid','P','Partially Paid','Not Paid')
SELECT SUM(AID.AMOUNT),
DECODE(APS.PAYMENT_STATUS_FLAG,'Y','Paid','P','Partially Paid','Not Paid')
FROM PO_LINE_LOCATIONS_ALL PLL,
PO_DISTRIBUTIONS_ALL PDA,
AP_INVOICE_DISTRIBUTIONS_ALL AID,
AP_INVOICES_ALL AIA,
AP_PAYMENT_SCHEDULES_ALL APS
WHERE PLL.PO_LINE_ID = :B1
AND PLL.LINE_LOCATION_ID = PDA.LINE_LOCATION_ID
AND PDA.PO_DISTRIBUTION_ID = AID.PO_DISTRIBUTION_ID
AND AIA.INVOICE_ID = AID.INVOICE_ID
AND APS.INVOICE_ID = AIA.INVOICE_ID
AND AIA.CANCELLED_BY IS NULL
GROUP BY DECODE(APS.PAYMENT_STATUS_FLAG,'Y','Paid','P','Partially Paid','Not Paid')
The reason seems to be that the Session Browser query:
SELECT REPLACE(q.sql_text,chr(0)) sql_text
FROM v$session s,
v$sql q
WHERE s.sql_address = q.address
AND s.sql_hash_value = q.hash_value
AND s.sid = :SID
is picking up all the different child number queries from v$sql, is there anyway to only pick up the child that you are using to avoid the strange query output?
Thanks in advance

Hello All;
The front end is Oracle Forms/ Reports 6i Patch 16.
I will try TKprof.
I found here someone asking on the same case,
Database is too slow.....
He was advices to 1- Compute Statistics 2- reorganize tables 3- re-build indexes
I done it in the order a-Import Tables b-Rebuild indexes c-Compute Statistics.
Shall I do it in order 1 2 3 ? or 1 & 3 will be ok?
Can I issue
sql> Alter table <name> move tablespace <tablespace_name>;
on the original tablespace or I need to provide new tablespace?
Best Regards,
