ODBC and Network Waits

I have an application that uses ODBC and c++ ,i have checked the network latency and it is acceptable but the database as a whole  shows high wait levels of 
 
  SQL*Net message to client                            
  SQL*Net more data to client                                    
  SQL*Net message from client

I have traced  one slow SQL with TKPROF and i found a high cpu for parsing and fetching but also i found these wait events only.
 

My question has any one faces related problems to ODBC for example bugs,data send and recevied ,network....  i want to be sure it is only an application problem.
 

Oracle 10g, Windows server 2003
 

Thanks
