Hi. I did this and it worked. Thanks.

However it appears that what I really want to do is impossible - lock the entire document and yet still allow the user to use hyperlinks. I wonder why it is (apparently) not possible to do this. Or, more generally, why must the user be "forced" to the first form in a protected document (on mouse click) when that user may well wish to "navigate" through the document using the cursor?

I realize, of course that the user can indeed navigate through a locked document using the arrow keys. However, I suspect you will agree that users are deeply accustomed to using the mouse (with clicks) to navigate through a document.

Obviously the advantage of the present functionality is that users more or less cannot help but go to the first form in a locked document. Fair enough, but this also robs the user (in my view anyway) of the highly desirable capability to otherwise navigate freely through a locked document using the mouse buttons. Perhaps the reasoning is as follows: If users are allowed to "click their way" through a locked document, they will expect to be allowed to alter that document.

Anyway, I very much appreciate your assistance and suggest this item is "solved" (in the sense that it appears that you have given me the "best possible" solution to my problem, even if it is not strictly what I was hoping for).
