Expanding or Collapsing Orders was seemingly erratic in the Status Screen. The "NEXT" order(status) and the order after it were the only orders to experience the issue. There was some errant code that was attempting to expand these two orders when the screen auto updates itself that was working against the Expand Collapse function. The expanded state that is saved with the order record was being modifed without also forcing a refresh of the tree. This resulted in actual state of the controll not being in sync with the state of the order and caused the flaky behavior.
