This is an enhancement for the FindReplaceDlg so that it saves the find dialog relative position to the main notepad window. This comes in handy for multi monitor users where you decide to move the app to another screen then CTRL-F to search but have the find dialog pop up on the old screen.
Useful for people that like having there find dialog in a certain spot relative to the main app regardless of where you move it.
Note that this doesnt save the relative position after closing the app. It defaults to center as before when its first created.
