SYMPTOMS
Consider the following scenario. In Microsoft Windows Media Encoder 9 Series, you use the screen capture tool to encode content. During this process, you double-click a control on the screen. However, the control that you double-click does not respond as expected.

Note The control does respond to single left-clicks and to single right-clicks.



CAUSE
This issue occurs when you encode content by using the screen capture tool. When you use the screen capture tool in this manner, the WM_SETCURSOR message is repeatedly sent to the message queues for the controls in the screen capture. Typically, the WM_SETCURSOR message is sent only when you move the mouse pointer over a control. However, when you encode content by using the screen capture tool, the WM_SETCURSOR message is sent even if you do not move the mouse pointer. When the WM_SETCURSOR message is repeatedly sent, the message queues for the controls are flooded, and therefore the controls cannot correctly read the number and manner of mouse clicks.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the &quot;Applies to&quot; section.
