#106 Gui fails if running in computer accessed by windows remote desktop session and session disconnects

[Alister Hood]

Hi, running on Windows 10:

• I connect via Windows remote desktop client to another computer
• run pdfsam there
• close the remote desktop connection
• either reconnect or go and log on locally to the machine I was logged on to remotely.
  The pdfsam gui no longer works - the main window doesn't update, and is invisible if pdfsam was underneath another window when the remote desktop connection was closed.
  This is an issue with recent pdfsam versions, but not with 2.2.x, so I'm guessing it is an upstream issue with JavaFX.

By the way, if you're wondering why I use the remote desktop connection, I have a VPN but if I run pdfsam on the local machine it gets stuck if I try to save outputs on a remote server. But I know the VPN is unreliable, and I don't know if this would still be a problem with a more reliable VPN.
