Mouse actions are blocked when you create a new virtual desktop

Symptoms
When you create a virtual desktop on Windows 8.1 or Windows Server 2012 R2, you expect mouse actions to work similarly to how they work in earlier versions of Windows. However, mouse actions may be blocked. For example, clicking the mouse pointer does not stop the installation process when you create a new virtual desktop.
Cause
This problem occurs because the mouse hooks are invoked across desktops.
