Hi All,

I am trying to create an Undo function
for one of my stacks.

Not sucessful at all. Everything seems so simple,
but it failed everytime.

The model that I am using for this task is the
"History palette" used in Photoshop:

Now, I am asking for advice from all of you
that have created similar function for your
applications or stacks.

Thanks in advance!
