In one of my PHP page I open a popup (window.open(...)) whern the user cliks on a button.
I'd like to close this popup window when the focus is not on this window anymore, i.e when the user has clicked on another window, and thus the popup window is not anymore on top.
So that I could re-open the pop up as many times as the user clicks my button, avoiding him to look for the popup window in the taskbar.
Hope I've been clear...
Thanks for advance,
