[Javascript] window closing

[javascript@xxxxxxxxxx (sebastian)]

Hi.

On my page I'm using JavaScript to open a new window (let's say win1) just
before I submit a page.

win1=window.open ....
document.xxx.submit()

How to close this window when the user actualy navigates to the next page.

I tried to use win1.close() on onUnload ewent but because the two statements
are not in the same function en error occur ( win1 is not an object...)

I'm using this page to upload a file to the server using a Dundas upload
component and I want a message to be displayed (new window) while a file is
uploading.

Thanks, Sebastian
