SYMPTOMS

You develop an application that uses the SetCursorPos function to change the pointer position on the screen. Then, you use Remote Desktop Connection (RDC) to connect to a Windows-based terminal server from a client computer that is running Windows Vista or Windows Server 2008. When you run the application in the Terminal Services session, the pointer position behaves incorrectly.

This problem may occur when you try to move the pointer over the edge of the Remote Desktop window.

CAUSE

This problem occurs because the RDC client does not include the last pixel in the Remote Desktop window as part of the Remote Desktop window. Therefore, the function does not work correctly.
