New ActiveX Control popup

[Guest]

I have recently installed an Excel Service pack and I'm now finding a new
popup every time I open a particular file. This file contains a refrences to
several activeX controls. The popup states:

Application is about to initialise ActiveX control that may be unsafe. If
you trust this source blah, blah, ..... [OK] [Cancel]

Any questions regarding security tend to really freak out my users so I'd
like to stop it.

I have found that if I remove a particular form from the document then the
message doesn't occur. That form contains a refrence to the Microsoft
RichTextBox contol in richtx32.ocx. I don't understand why a MS-made control
would be considered unsafe but I'm reasnibly sure that's the problem.


I'm guessing there is no way that I can supress this message because it's
related to a security issue. Is there something I can do to so that Excel
will consider control safe? Prehaps I need to digitally sign it? What's the
trigger for this popup?

Thanks Peter, you're right though; that doesn't make me very happy at all. It
looks like I might have to dust of the old copy of VB6.
