Fixes are :

Fixed : Bug where on cancelling an Add or Add Copy Item dialog, if you clicked the red cross to close the dialog box, you got an access violation
Fixed : Creating a new project would not add it to the recent projects list.
Fixed : Would save the project multiple times when multiple windows were saved at once.
Fixed : Undo on sprite window would not update title bar with asterisk to say the file was changed
Fixed : Access violation when selecting properties for new sprite and the sprite collection not yet saved.
Fixed : When closing windows Project items would all be collapsed. Now stays open
