title: Can't resize or move windows on Raspberry Pi
body: <p>I am using the Raspberry Pi Model 3 B+ and there was recently an update( I did not record what it was doing or what it was called) and upon reboot it mentioned that there was a previous version saved somewhere(did not take note of where this was at). Not thinking much of the update I tried to move windows around and they would not move. I found to try the <em>Alt</em> button and dragging and that is not working.</p>
  
  <p>When I open up a tab for the terminal, or Idle the window drops down in the top left corner below the taskbar. When the internet is opened the window appears the top right corner. When texteditor is opened it is opened with only a little of the top of the window showing in the bottom of the screen.</p>
  
  <p>I am using HDMI connection to a Sony TV, 2.4G Keyboard. Not sure what other information you will need. Along with this update the Raspberry Pi "Berry" in the taskbar has dissappeared and replaced with an imaginary icon. Any suggestions?</p>
