How to disable automatic report generation when report opened?

Hi all,

I have a report I'd like to open in 'dormant' mode initially. ie the user has to click 'view report' to generate the content.

The only way i've been able to achieve this is to add a parameter and set it to not allow nulls and set the initial value to be null.

I can live with this for now because the report has a datatime paramenter so the above hack is transparent I'd like to have the default value set to Today(). But this causes the report to fire and generate automatically when it is opened.

This is in 2005
