The environment always plays a role in the way a computer application
behaves, particularly on Linux/Unix systems.
GAMGI works fully well with 
Enlightenment (tested on Yellow Dog Linux 2.2 for Mac and Suse 10.0
Linux for PC) and 
Blackbox (tested on Mac OS X with 
Fink).
Window Maker (tested on
Yellow Dog Linux 2.2 for Mac and Suse 10.0 Linux for PC) and
Twm
(tested on Yellow Dog Linux 2.2 for Mac and Suse 10.0 Linux for PC)
keep showing the windows decorations, in fullscreen mode.
KDE (tested on Yellow Dog Linux 2.2
for Mac) and 
GNOME (tested on Yellow
Dog Linux 2.2 for Mac) also keep showing the windows decorations, in
fullscreen mode. Moreover, KDE does not define the 
WINDOWID
environment variable, so the 
Console button (in the window
tools section) cannot work and GAMGI hides it.
