An assistive technology product does not detect Windows events in Windows 7

Symptoms
Assume that you run multiple assistive technology products at the same time on a computer that is running Windows 7. In this situation, an assistive technology product does not detect Windows events.

For example, consider the following scenario:
  1. You start Microsoft Magnifier.
  2. You click to select the Follow the keyboard focus check box in the Magnifier Options dialog box.
  3. You start Microsoft Narrator.
In this scenario, Magnifier does not follow the keyboard focus.
Cause
This issue occurs because Microsoft Active Accessibility prevents User Interface (UI) Automation from handling the WM_GETOBJECT message that is associated with Windows events. Instead, Active Accessibility tries to handle the WM_GETOBJECT message itself. However, Active Accessibility does not trigger Windows events. Therefore, Active Accessibility cannot handle the WM_GETOBJECT message and this issue occurs.

Windows 7 file information notes
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductSR_LevelService branch
    6.1.760 0. 16xxxWindows 7 RTMGDR
    6.1.760 0. 21xxxWindows 7 RTMLDR
    6.1.760 1. 17xxxWindows 7 SP1GDR
    6.1.760 1. 21xxxWindows 7 SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
