	Hi Stoyan, I noticed that when you zoom in the diagram, it always use the top-left corner as zooming focus. Is there any way to change that to center of diagram? Like google map is doing. And another question about active item for selection of multiple nodes. Any way to stick the active item to the first selected node(currently the active one is the last selected). I know this looks some irregular - but users get used to our previous version which was developed with other diagram component. If there's any easy way, please let me know. Thanks. Kyle

	Hi, The MouseWheel handler here shows how to zoom with a specific point remaining in place: http://mindfusion.eu/Forum/YaBB.pl?num=1225423028/2#2 To keep the oldest item the active one, try handling NodeActivated and LinkActivated like this: Code private void diagram_NodeActivated(object sender, NodeEventArgs e) { if (e.Node != diagram.Selection.Items[0]) diagram.ActiveItem = diagram.Selection.Items[0]; } I hope that helps, Stoyan
