thanks for the fast response.
my prob is, i had to put the possibility of sound in the site, and i dont want to use frames.
so my idea was to put it into a popup that can be closed by a button from every site of the project.
now it works only if the open button is clicked first (i think so a focus is set on the popup window)
i've thought perhaps it is possible to set the focus on the window and close it only by clicking on the close button.
ok hope you will find any ideas
i will google a little bit...
