I have a UI dialog that I want to present a "warning" popup when a field is 
blank.  The dialog is launched with SpawnDialog and says something like "Do you 
really want the field empty?"  There are two buttons labeled "Yes" and "No".  
If the user picks "No", it's easy enough to close the popup and return to the 
parent dialog with the usual "EndDialog" event and "Return" value.  However, I 
can't seem to find a clean way to close the popup and still move to the next 
dialog.  There doesn't appear to be any other value I can pass to EndDialog 
that would do this.

I came up with a solution that kinda works.  Instead of using SpawnDialog, I 
use SpawnWaitDialog.  Then in the popup, I set a property when the user clicks 
either button.  This property is the trigger condition for the wait dialog.  
The approach works, except that the cursor changes to the wait icon (spinning 
circle or hourglass) - which makes it unclear to the user that they need to 
press a button.  Is there any way to change the cursor manually?  Perhaps in a 
custom action?

Is there a better approach to this?

Thanks,
Matt
