Dialog Stack Design Questions

[Len Morgan]

I'm wondering what is the "recommended" way of handling a lot of dialog 
boxes in applications.  There are a couple of way of handling this that 
I've thought of but I don't know what would be considered "best:"

1) A separate stack for each dialog.
    Pros: Sizing, function (information only, getting user input, etc) 
can be implemented without worrying about it's effect
             on other dialogs.
    Cons: You need the basic "stack overhead" repeated over and over for 
each dialog

2) One dialog stack with multiple cards (one for each dialog).
    Pros: Single stack overhead (smaller file size)
    Cons: Every time a dialog is opened, the correct card has to be 
selected and then the stack has to be resized for that particular        
      dialog.

3) Some other approach.

Any advice? I know I could use either one and make it work but I looking 
for "best practice" advice.


Thanks!
