>I have a very busy form with some object enabled, some disabled, some visible, some invisible, ect.. If the user clicks on a button, I want to disable everything that is enabled, perform that particular method and return to the previous state. What is available which lets me do this (kind of like to 2.6 SAVE SCREEN, RESTORE SCREEN commands)?

You can loop through Form.Controls collection (checking containers too) and populate some form custom property-array with current values of 'Enabled' properties. So, you will do it twice: to collect values and to bring them back to properties. Do it once, save it as Custom object method, and use it for any form.
