>Just thinking outloud but could you instanciate a modal form class (with a user-friendly please wait message on it) with no close button and no other way for the user to exit the form while the process is ongoing. When your Excel processed is finished, you could release the form.

The problem is knowing when Excel is finished. I ran into the same problem with a Word process, and resorted to solving it with a simple delay. Some of this can be solved with settings in the server app. For instance, I got around another situation in Word by temprarily turning background printing off, which made the first process effectively modal.
