Buenos días! tenia una consultilla para aquellos q controlan con javascript (Q supongo será el caso).
Necesitaba crear un pop up de un tamaño determinado al pulsar sobre un link...
Con el minimo marco posible, es decir la cabecera con la cruz y punto 
.
Gracias por adelantado.

Lo saque de no se donde hace tiempo (era de codigo libre), sacalo editando... el segundo post es el archivo pz_chromeless_2.1 (SRC="js/pz_chromeless_2.1.js") que es el nombre del popup este.
Es muy bonito de ver y queda de muerte en paginas integramente en flash que vayas a abrir en plan popup..., ademas de poder personalizar los botoncitos de cerrar y su icono... 
como os liais, hay generadores de pop ups, buenisimos que te centran la ventana y tal y es compatible con IE y Mozilla Firefox:

1 saludo.
Supongo que sabéis que esas cosas dejarán de funcionar en el Explorer con el service pack 2 de Windows XP ¿verdad?
si,al igual que ya pasó con el sp1, la chromless, dará problemas.
decir que ya han sacado una version del script compatible con mozilla,pero por el momento, solo la sueltan a cambio de pasta :S
la url: www.chromeless.org
yo los veo bastante utiles en algunas circunstancias. Los van a suprimir completamente? Ome podrian dejarlos con ciertas limitaciones para q no se abuse de publicidad con ellos...
Hay que abrirlos de una forma especial y se pueden desactivar por completo (de todas formas siempre se ha recomendado no abrir ventanas nuevas...)
gracias a los dos. He lograo un resultao ya curioso
