Can form-dialog have a "please wait" property until an action is completed?

[aykaramba]

I am using form-dialog boxes in various places to:

1. Present a set of options a user can choose from while making the rest of the page "inactive".
2. Based on user choice, some actions are activated, processed and an alert dialog is presented confirming the action has completed.

PROBLEM: Step 1 and 2 both grey out the entire page making it inaccessible to users and maintaining focus on either dialog box. However, in between step 1 and 2 above, the entire page becomes active (the dialog in step 1 disappears) allowing a user to click on the application interface before the step 2 alert box is triggered. If step 1 triggers actions that take a bit of time to complete (let's say a few seconds) and the dialog box disappears, it can be jarring for users to be clicking around the application interface only to suddenly have the step 2 alert box render notifying them the action has completed.

QUESTION: Is there a way to unify the dialog boxes in step 1 and step 2 and insert an intermediate dialog box that provides some sort of progress message while the entire app interface is greyed out?

Any suggestions on how to approach this would be great.

For anyone wondering about form-dialog, you can find sample code in 22-tutorial.lisp. Here is sample code for reference:

(form-dialog this-view "Please enter your information." ;; sample found in clogs 22-tutorial.lisp
                    `( 
                       ("This question." "value" :radio 
					         ("Eyecolour" "brown")
						 ("Number of fingers" 5)
						 ( ... etc ... )
                       )                 
                     )
                     ;; results confirmation
                     (lambda (results)
			     ;; do some stuff
                             (alert-dialog this-view (format nil "Documents successfully uploaded to: ~a" (some code)))
                             )
                     ;; dimensions
                     :height 550)

Closing this for now. In the future perhaps I can create a version of the dialog that addresses this. For now I will use a different approach. Note to anyone reading, nothing here suggests form-dialog has a flaw, only that an additional dialog with additional properties would be a useful addition in the future.
