Good morning,

I hope, this post will help to understand my problem/appraoch.

That's what I did: I downloaded the linked file, did nothing but protect the file (allow form fields only) and clicked some check boxes. The protection makes the selection change from the just selected check box to the next check box.

This automatic 'change selection' behaviour triggers the further actions. Basicly perfect, BUT I'd like to have the just selected check box to be selected (again):
1. user clicks (selects) check box which leads to
2. an automatic selection change (to next check box) as the document is protected
3. then back to previous check box to pretend an ActiveX radio button behavior.

I simply do not know to return to (address) the previous check box.

Hope it's a bit clearer now.
