Experiment Tree View sometimes does not display the detailed content

[abeham]

Sometimes it does not display the content properly in the details pane. I had this behavior on two different computers so far.

It seems to occur on release builds more often than on debug builds. Nevertheless I could reproduce this on a debug build:

1. You need to start with the debugger attached
2. Put a breakpoint at the beginning of treeView_MouseDown and treeView_NodeMouseClick.
3. When you click on a node in the view the mouse down breakpoint will be hit
4. Continue with F5 and you'll see that the node mouse click event will not be called.
5. You can check in the view that the details pane is empty
6. If you remove the breakpoint in treeView_MouseDown it works as expected.

I have no explanation for this kind of behavior. The two events seem to be in competition to each other. I would advise to put all functionality in mouse down.
