qjoypad window does not show up when run

Description: Ubuntu 14.04.1 LTS
Release: 14.04

2) apt-cache policy qjoypad
qjoypad:
  Installed: 4.1.0-0ubuntu1

3) What is expected to happen when one installs via the standard Ubuntu ISO (not Kubuntu), and logs into gnome-session-fallback, is that when one runs the qjoypad, either a taskbar icon shows up, or preferrably the GUI window shows up as viewed at http://qjoypad.sourceforge.net/#screenshots .

What happens instead is first, the default GUI launch icon looks as if no icon is associated with it (not the scope of this bug report). Next, when one clicks it, no window ever opens. If one attempts to launch it again, it notes in a popup window:
QJoyPad 4.1 - Instance Error
There is already a running instance of QJoyPad; please close the old instance before starting a new one.

WORKAROUND: What one may notice is the network icon in the System Tray moves over to the right 0.5 inches, with a blank space. However, if one clicks this newly created space, then the program window opens as per attached systray.png .
