When I call the on-line help, Windows XP says he has blocked the active content! What is the problem?

With Windows XP Service Pack 2, security options are enforced. By default, Internet Explorer stops the execution of Javascript code because it may contain threats. In the Shadows on-line help, Javascript code is used to display the frame and title of the page, as well as to select styles. There is no security risk in this case and you can click on the message on the top of the page to allow the active content and therefore allow the page to display itself correctly. This problem is found the first time Internet Explorer opens a help page. Other Windows versions are not concerned by this problem.

A good way to solve this problem is to use an alternative Web browser, such as Firefox. It is a free browser that offers a lot of advantages compared to Internet Explorer, in particular it does not block the Shadows help (though it contains a ad pop-up blocker).

My firewall program has detected that Shadows tries to connect to Internet! Does it contain a virus or a spyware?

Shadows periodically checks if a new version is available on the web site To do so, the program detects if an Internet connection is active and consults a file containing the available version. So it is normal that Shadows establishes a connection. There is no risk for your computer, Shadows does not contain any virus and does not try to send personal information on the Internet. Normally the verification is a transparent mechanism for the user, even if no connection is there. But if your computer is protected by a firewall, the connection will be detected and you will be notified. It is therefore recommended to configure your firewall and authorize Shadows to use Internet.
You can also disable the automatic mechanism in the General Preferences
