Remarks:
When adding several groups and objects at once, it is best to call EnableRedraw (FALSE), before starting to add items to the tree, along with EnableRedraw(TRUE), after you have finished adding those items. This prevents a flashing effect and the constant repainting of the tree in the Information Window. Instead, EnableRedraw repaints the tree once all the items have been added.
