Is it a standard Windows Class, or a custom control? Have you already
tried mapping the Class to the TreeView object type?

If you cannot get Robot to recognize this TreeView control as a standard
Object Type, you may be able to navigate "blindly" if it supports keyboard
shortcuts (not likely). See if you can do the required actions (manually)
using only keystrokes. If you can, map this control (Class) as "Generic",
and use InputKeys to execute the keystrokes.

If this fails, you could make this part of the test interactive (manual)
by displaying a MsgBox prompting the tester to perform the actions, then
click some button to continue the automated test. Maybe later, you will
find a way to automate this part...
