Beta 4:

• rawinput was not enabled properly in all situations (mainly affected -rawhid parameter)
  
• write log message if D3D command pipeline flush fails or is not supported (tearing in new vsync mode)
  
• added win32.gui_page= configuration entry, selects default panel when GUI opens
  
• magic mouse in fullwindow mode only uncaptures if mouse would move to another monitor
  
• quickstart mode now sets sound mode to "disabled but emulated" if it was "disabled", previously it was always set to "emulated".
  
• CD/CD image switching on the fly was unreliable (different problem than b2 fix)
  
• optimization that detects if sprite changed has not been working for ages
  
• sprites above or below bitplane area and AGA border sprite bit set caused graphics garbage around the mouse cursor in some situations.
  
• possible fix for autoresolution aspect ratio problems when filter aspect ratio setting is enabled
  
• removed default scroll lock -> inhibit screen updates key mapping
  
• AROS ROM updated

Remaining new vsync updates coming later...
