Bug in options of backup

1) Platform : Windows XP;
2) Language : Portuguese;
3) Distrituition: binary:
4) Version 1.2.0.

The GUI allows to choose to create and to exclude tables and datababase 
of simultaneous form.

It would have to incapacitate the conflicting options

The error below occurs:


C:\Arquivos de programas\PostgreSQL\8.0\pgAdmin III\pg_dump.exe -i -h 
localhost -p 5431 -U postgres -F p -C -c -v -f "teste2.sql" -t teste1 teste
