	Hi, I have a problem with library, I should show a messagebox when I click a button in my form. The problem is that this warning is below my form and my diagramview. Instead: Code diagramView1.Hide(); MessageBox.Show("Pluto", "Output"); diagramView1.Show(); I try this and it is right behaviour but I want see also the diagram when I see this warning. How could I do?

	Hi, I can imagine this happening if your diagram view is in a different form than the one displaying the message box. In such case try setting it as box' owner - Code MessageBox.Show(diagramView1.Parent, "...", "..."); // or maybe MessageBox.Show(diagramView1, "...", "..."); Regards, Slavcho Mindfusion

	I tried this but It is not working. If I don't draw the node it is right behavior instead if in my diagram exists a node, It is not working the messagebox is drawed below my form.

	There are plenty of message boxes shown by diagram's sample projects, e.g. Floorplan Designer's 'door must be dropped on wall' message - don't these show on your system? MessageBox being a top-level window should not be able to hide behind a child DiagramView of a form while still on top of the form. So you either have multiple forms and diagram's one activates while drawing the node, or otherwise there is some strange top-most flag set on the single form. If using ControlNodes, see if hosted control isn't creating a topmost HWNDs in addition to the child control. You could use WinSDK's Spy++ tool to check both.
