o General NxWM Issues
  -------------------

  Title:       DISPLAY INITIALIZATION
  Description: During the initialization of the display, the basic frame of the
               start window is drawn momentarily.  This is just the empty window
               frame.  This is a consequence of how NX creates windows:  The
               are enabled all of the time so the windows are visible when they
               are being created. The solution would be to add some disable
               logic in NX so that that nothing gets displayed when a window
               is created until it is fully initialized and enable.

  Priority:    Medium

  Title:       DRAGGING ACROSS WINDOWS
  Description: Need some indication if the touch/mouse drags from one window to
               another then is release.  Release event is lost in this case.
  Status:      Open
  Priority:    Low.  ICON just stays selected and must be touched again.

  Title:       AUTO-RAISE DISABLED
  Description: Auto-raise is currently disabled in nuttx for NX multi-server
               mode.  The
               reason is complex:
               - Most touchscreen controls send touch data a high rates
               - In multi-server mode, touch events get queued in a message
                  queue.
               - The logic that receives the messages performs the auto-raise.
                 But it can do stupid things after the first auto-raise as
                 it opperates on the stale data in the message queue.
               I am thinking that auto-raise ought to be removed from NuttX
               and moved out into a graphics layer (like NxWM) that knows
               more about the appropriate context to do the autoraise.

  Priority:    Medium low

  Title:       COMBINE CTouchscreen AND CKeyboard THREADS
  Description: Right now, two separate threads handle touchscreen and keyboard/
               console input.  Each just waits on read() and when toushcscreen
               or keyboard input is received, it injects the data into NX.
               These two threads should be combined into one thread that waits
               on poll for read data from either device.  Then when read data
               becomes ready for either device, it could perform the read and
               data inject from a single thread.
  Status:      Open
  Priority:    Low, this is not a product but a  text example.  If NxWM were
               to be productized, this change should be done in order to reduce
               stack memory consumption.

o CHexCalculator Issues
  ---------------------

o CMediaPlayer Issues
  -------------------

  Title:       SCROLLING FILE LIST
  Description: Current implementation uses a CListBox which can only show a
               fixed number of files.  Perhaps CMediaPlayer should use
               something like CScrollingTextBox.
  Status:      Open
  Priority:    Low for now

  Title:       PLAY PROGRESS FEEDBACK
  Description:  Need a way to know the position in the file, how long the
               file is (in minutes), and an indication when playing
               complete.
  Status:      Open
  Priorit:     Medium.  Certain affect usability.

  Title:       NO BALANCE/TONE/EQUALIZER CONTROLS
  Description: The title says it all
  Status:      Open
  Priority:    Medium.  That is big functional limitation.
