SYMPTOMS
Consider the following scenario.
 * You type a keyboard shortcut on a Windows Vista-based computer.
 * You are working in a Terminal Services session that was started by using Remote Desktop Connection 6.0 (RDC 6.0).

In this scenario, some keys in the keyboard shortcut may remain active. Therefore, in the Terminal Services session of the Remote Desktop window, some later keystrokes are interpreted as part of the previous keyboard shortcut. For example, this problem occurs if the following conditions are true:
 * You lock the local computer by pressing the Windows logo key+L keyboard shortcut.
 * You unlock the local computer.
 * The Remote Desktop window is active.

When you press any key, various Windows keyboard shortcuts occur in the Terminal Services session. For example, when you press E in the Terminal Services session, Windows Explorer starts as if the Windows logo key is still held down.

Note Windows Explorer should start when you press the Windows logo key+E keyboard shortcut.



CAUSE
This issue occurs because of an error in Remote Desktop Connection 6.0. When you press a keyboard shortcut on the local computer, Remote Desktop Connection 6.0 may send only the &quot;key-down&quot; message to the remote session. Remote Desktop Connection 6.0 may not send the &quot;key-up&quot; message for certain modifier keys such as the ALT, SHIFT, and Windows logo keys.
