Subject: Re: [cgmo-webcgm] IE ActiveX Update

[sent on behalf of Ralf]

Hi All,

let me clarify one detail. After installing the so called "IE ActiveX
Update" the initial display of embedded CGM objects is not affected. The
update only prevents the automatic user interaction with the embedded
object. So we don't see any interactivity (events, tooltips) without
activating the control.

The same restrictions appear for other embedded ActiveX controls as well
(e.g. SVG Viewer, Flash).

Details can be found in the MSDN article "Activating ActiveX Controls"

Best Regards,
- Ralf
