We have a strange problem under Windows Server 2012 foundation. All latest Auto updates are installed.
We start an RDP session, and everything works ok. The problem is that in the moment we open certain apps, mouse stops working, and only keyboard works.
So far, I've detected this happens when I open SQL Server Management Studio, and also happens when I open Microsoft Dynamics NAV 2013 client.
We are still able to see the cursor, but mouse clicks don't work. At this moment we can only use keyboard to do anything in the session.
