This is a JavaScript question. Moved to that forum.

Welcome to JavaRanch "kill factory".
No doubt you clicked on something called the JavaRanch naming policy when you signed up. Could you please take a minute to change your display name to show a name, preferably your real name? You can do that right here. It's all about maintaining our professional image - don't let the one-eyed moose fool you!

That is put there for a security reason so that you can not close the window since people like to keep their surfing history...
Is there a way around this? Yes....
