A VB6 application that I am supporting uses the web browser control to
view/edit word documents from inside the application. One of the main
features of this application is to provide the user with mail merge
functionality without having to launch Word separately.

This approach has been working fine for years - right up until Word 2003.
It appears that if you have Word 2003 and you open a Word document with the
web browser control or Internet Explorer itself, the mail merge toolbar will
be disabled.

Is there a work-around for this? I have tried the SQLSecurityCheck registry
key but all it does is prevent the prompt "Opening this will run the
following SQL..." from popping up.

The problem is occuring with Windows 2000 and Windows XP with Word 2003.
