Tabbing has gone to an element outside the target hwnd.

Type

Error

Description

Using standard keyboard navigation (Tab or Shift+Tab) causes focus to shift outside the HWND of the verification target.

AccChecker moves up the element tree to the top-level HWND for the chosen verification target before running any verification tasks. This reduces the number of spurious errors generated if an HWND chosen for verification is part of a more complex client area.

Possible causes

  • The verification target doesn't require a tabbing implementation to provide full functionality.
  • User interaction during verification, such as moving focus to a non-target HWND, interfered with the verification process.
