Fix for jerky mouse movements in remote desktop/Citrix sessions to Windows Server 2012

When connecting with Citrix to a Windows Server 2012, you might experience that the mouse pointer is lagging severely causing a jerky movement and making it a complete dud trying to make any proper work on the server.

If this is the case, you should make sure that the Enable pointer shadow checkbox in the Mouse Properies is unchecked. This feature has been the issue with many machines I've encountered lately and unchecking the property has made the UI more enjoyable.
