Hi Alfred,
The radio buttons (which you must have gotten from the Control Toolbox
toolbar, since the Forms toolbar doesn't contain any) are ActiveX controls.
For purposes of security, Word treats all ActiveX controls the same as
macros, as potential virus threats. You have your macro security level (in
Tools > Macro > Security) set to High, which automatically disables all
macros and ActiveX controls upon opening any document that contains them.
The appearance of Design Mode is a side effect of the disabled controls.
You can change your security level to Medium, and then each time you open
the document you'll get a dialog asking whether to disable or enable macros.
If you choose Enable, the document will open normally; if you choose
Disable, you'll be dumped into Design Mode.
The same is true on any other machine to which you send the document. As the
author, you can't affect how their security level is set -- you'll have to
include instructions when you send the document, asking each user to set the
level to Medium and click Enable on opening the document. Yes, this is a
pain, but you can thank your friendly virus writer for the necessity.
Protecting a document for forms is an entirely different process and has
nothing to do with ActiveX controls. If you've used other controls from the
Forms toolbar, then you have to use the Protect button on the toolbar or the
Tools > Protect Document dialog to make the forms controls work. If you
assign a password in that dialog, anyone trying to unprotect the document
will have to supply the password (although there's an easy way around that
if you know what you're doing). If there is no password, just click the
button again or use Tools > Unprotect Document.
