Hello

Sorry for asking these questions. I am just a demo page ....

Note: This code does not work in IE 7, due to a security related bug. IE will ask a question you never can answer. The default behavior of IE can be changed in Tools > Internet Options > Security > Personalization. Somewhere you have to enable this JavaScript function. E.g. search for something like 'Authorize websites to prompt for information using scripted windows'.
