Hi,
Every window you create with JS will exist as reference, even if it is
closed already, so testing for a windowref will not help.
BUT: Every window has a property (read-only) called 'closed'.
If this is set to true: window is closed, else it is still open.
if (mywindowref.closed){
// window closed, reopen it
...your code
} else {
// window open, focus to it.
....
}
