Couldn't method from base class scan all associated editable UI elements
(members of the window) and store their values just after window opening?
Also, I believe there must be some event fired on closing window, also
processed by this base class. It's good place to do comparison.
Just ideas. I'm sure you know the architecture better.
with regards.
