SYMPTOMS
When you open a document that contains an ActiveX control in a Microsoft Office 2003 program, you may receive the following message:

An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?

If you click Yes, the file loads with full functionality.

If you click No, you receive the following message:

This page provides potentially unsafe information to an ActiveX control. Your current security settings prohibit running controls in this manner. As a result, this page may not display correctly.

Note If you open the document in a Microsoft Office XP program, you are not prompted with these messages.



CAUSE
This behavior has changed from the behavior in Microsoft Office XP. An ActiveX control that has not been registered as a Safe For Initialization (SFI) control and does not implement IObjectSafety will be treated as an Unsafe For Initialization (UFI) control and you will be prompted to load the ActiveX controls.



WORKAROUND
To work around this behavior, when you create your Office document that contains ActiveX controls, use a comparable control that is included with Forms. For example, if you use a custom tab control in your document, use the Forms Multipage control instead.
