Warning for users XP with servicepack 2 and internet explorer

This notes are only relevant for users having problems loading VRML or X3D files from
within Internet Explorer on Windows XP systems. Users who don't have Windows XP
or have not downloaded Service Pack 2 for Windows XP or are using the stand-alone
version of BS Contact VRML/X3D don't need to read this.

Coming with Service Pack 2 for Windows XP, Internet Explorer has a slightly changed
security policy regarding content. The stand-alone version of BS Contact VRML/X3D loading
content from the local harddisk drive, including CD-ROM and network drives starts up automatically
as expected. However when Internet Explorer is prompted to load a local VRML or X3D file, either
directly or embedded into an HTML file, it doesn't load BS Contact automatically. Instead, it displays
a yellow bar on the top of the window that warns about potentially unsafe content (figure 1a). The first
time this happens, a dialog box introduces this new yellow bar (figure 1b).

To view the VRML/X3D file, users must click on the yellow bar and allow BS Contact to load: When you
click on the yellow bar and a menu appears, select "Allow blocked Content..." and confirm the following
dialog box with "Yes". Another solution is to generally allow Internet Explorer to execute active content
when it comes from a local harddisk drive or a CD-ROM. To do this, start Internet Explorer, select the
menu "Tools" -> "Internet Options", then click on the tab "Advanced", search for the group "Security"
and check the lines "Execute active content in files from the local computer" and "Execute active content
from CDs from the local computer".
