Cannot visualize table

I cannot visualize the table:

CREATE TABLE public."Experimento"
( "id_Experimento" int8 NOT NULL DEFAULT
nextval('"ExperimentoSequencia"'::text), "id_Configuracao" int8 NOT NULL, desligar bool DEFAULT false,
"atualizacaoCliente"oid NOT NULL, "programaCliente" oid NOT NULL, "versaoCliente" float8 NOT NULL, prioridade float8
DEFAULT1, CONSTRAINT "Evolucoes_pkey" PRIMARY KEY ("id_Experimento"), CONSTRAINT "FK_EvolucaoConfiguracao" FOREIGN KEY
("id_Configuracao")
REFERENCES public."Configuracao" (id_configuracao) ON UPDATE NO ACTION
ON DELETE NO ACTION
) WITH OIDS;

I click on the button view data and it shows nothing. Not even the colluns.
I´m running the last pgadmin3 snapshot.
