Still no known way to *disable* the click-ahead, but here are a couple of
possibilities:

1. Create a small form with a label on it: "Please wait... updates in
progress...".
   Put your code into the form's Load event, and when the code is complete,
have the form close itself.
   When you want to run the code, open the new form modally (by specifying
WindowMode:=acDialog)

2. Suggestion by fellow MVP Ken Snell:
   Put a "big" command button (transparent) over the entire area of the
form
   (or over the command buttons). Make the button invisible initially. When
   your code begins running, the first thing to do is make the transparent
   button visible and bring to front. With no event procedures on the
button,
   the user can click all he/she wants and nothing will get through. Make
the
   button invisible when the code is done.

3. Suggested by Ken Snell and "Sco" Scofield:
   Have the code disable the buttons as its first step, and then
   enable them when done. You could loop through the controls (use Tag
   property value or control type).
