Close external window

[manolain]

Hello there

Could you please help me?
I have a web with several pages. In one of them, I do this:

informe=open("","informe");
this.focus();

And I leave the window opened to redirect there some links in the web

In the final document, the users go to after having clicked the end session button, I want to close the window 'informe' opened before by this simply code

informe.close()


But there is no way of closing the damned window. And what is worse, I dont get any javascript error message on the status.
Can anyone help me?Thank you very much indeed
