Hello, i've upgrade my version of goweb from 2.3.1 to Now I'm a problem because when i move an object in palette with nopost=false dont'work the function called by MyPalette2.SelectionMoved+=new EventHandler(MyPalette2_SelectionMoved); can you help me???? thanks bye

Are you saying that you have enabled the movement of objects in the GoPalette by setting GoPalette.AllowMove to true, and that your MyPalette2_SelectionMoved event handler is not being called? (The default value for AllowMove is false, and was false in 2.3.1 also.)
Had you also set GoPalette.NoPost to false? (The default is, and was, true for GoPalette).
