	We'll add some new properties to the ContainerFolded event-args object. Until then, you might store the original rectangles as Tag values. Stoyan

	I found some problems related to ContainerNode. 1. After I moved the nodes inside a ContainerNode to the ContainerNode's boundary, I couldn't collapse the ContainerNode with the expand/collapse icon. It seems that the ContainerNode was in moving mode. I need to get rid of the moving mode first then to collapse it. 2. I found several times that the nodes inside a ContainerNode disappeared after I changed position, expanded and collapsed(I didn't do anything special). I checked the nodes collection in the Diagram, all the nodes were still in the collection. But they were not drawn in the ContainerNode. I can't reproduce this problem, but it occurs quite often. 3. Links between nodes inside a ContainerNode can not be select, deleted. Because they are not shown inside the ContainerNode. These 3 problems are got from the FlowCharter demo projects. Would you please ask your testers to look at it? Right now, the ContainerNode is the only thing we can use to impplement subgraph. So it's very important to us. Thanks a lot.

	1) We've fixed a bug that might be related to this. Please try if this version of the control works better: https://www.mindfusion.eu/_temp/wpfdiag_ctrs.zip 2) Are you setting the ZIndex property of items in some event handlers? 3) The links should be seen, as long as you don't set their ZIndex to one lower than the container's ZIndex after the nodes have been added to it. In any case, you will need to set diagram.HitTestPriority = HitTestPriority.ZOrder to be able to select links inside containers. Stoyan

	Thanks, Stoyo. I'll try your new version and let you know the result. For the second problem, I didn't change ZOrder anywhere. It is Ok when some nodes are added to a ContainerNode. But suddenly, they are not shown in the ContainerNode when I expand it. Do I need to set ZOrder for the nodes when thet are added to a ContainerNode? For the third problem: after I added diagram.HitTestPriority = HitTestPriority.ZOrder, I can select a link. But If I click some white space in a ContainerNode the links are not shown(the ShapeNodes are still shown in the ContainerNode). I think it's better to show both ShapeNodes and Links in a ContainerNode. Thanks again!

	This version should fix the problem with the disappearing nodes: https://mindfusion.eu/_temp/wpfdiag_ctrs2.zip Stoyan

	Hi Stoyan, I got the following error after I replaced the dlls. Please tell me how to install the new dlls. Thanks a lot! Exception occurred creating type 'MindFusion.Diagramming.Wpf.Diagram, MindFusion.Diagramming.Wpf, Version=2.0.0.28641, Culture=neutral, PublicKeyToken=1080b51628c81789' System.TypeLoadException: Could not load type 'System.Windows.Media.Effects.Effect' from assembly 'PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

	Hi, The control now requires service pack 1 of VS2008 / .NET 3. The Effect class is defined in SP1 and replaces BitmapEffect. Stoyan
