When the Windows 7 taskbar is set to auto-hide and an MFC-wizard created SDI app is maximized (via a mouse click) , the Windows taskbar will no longer unhide when the mouse is moved to the bottom of the screen. (The little, telltale row of pixels indicating that the taskbar is hidden are also not visible.) If you restore the app's window, the taskbar still won't unhide. However, if you change the focus to another window, the telltale row of taskbar pixels reappear and the taskbar will unhide correctly.

This was problem was identified running Windows 7 Professional, version 6.1.7600 Build 7600. The app was built using Visual Studio 2010, version 10.0.30319.1 RTMRel. This problem was duplicated on a second computer.

(This issue was initially reported on the Visual C++ Developer Center Forum. You can read that thread at: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/3cafd80f-02bf-4dde-a5dd-89e93f64f3a4).

You can reproduce this in Windows 7 with the following steps:

1.     Crate a new MFC project.
2.     In Application Type, select Visual Studio.
3.     In User Interface Features, select Use a ribbon
4.     Click finish and build the application.
5.     Set “Auto-hide the taskbar” from the Taskbar and Start Menu Properties dialog.
6.     Run and maximum the MFC application.

The Windows 7 taskbar will not unhide when the mouse moves to the bottom of the screen.

When moving the mouse over the Windows taskbar (which was auto-hidden at the bottom of the screen), the taskbar does not unhide.

When the Windows taskbar is in auto-hide mode, the taskbar should unhide when the mouse moves to the edge of the screen where the taskbar is hiding.
