>When doing a first right click on a node the node is still expanded and the popupmenu is shown
>The second right click on the same node is ok ! no collapsing, just showing my popup.
>After collapsing the node with left click, the next right click on the same node is ok ! no expanding, just popup

I have the following properties set for the treeview:

Style: 7
Mousepointer: 0
Linestyle: 0
LabelEdit: 1
ImageList:
Borderstyle: 0
Appearance: 1
OLEDragMode: 0
OLEDropMode: 0
Indentation: 10
PathSeparator: \
HideSelection: F
Sorted: F
FullRowSelect: F
Enabled: T
Checkboxes: F
SingleSel: F
Scroll: T
HotTracking: F

I do not get any node expansion on the treeview with the right-click (left-click only).
