Comment 3 for bug 1688491

a better way - disable fullscreen mode:
create (or edit) the "options.txt" file in $HOME/.etr/ (where $HOME is your home folder)
with the following declarations:

# ------------------------------------------------------------------
# The first group of params can be adjusted
# on the configuration screen, too
# ------------------------------------------------------------------

# Full-screen mode [0...1]
  [fullscreen] 0

# Screen resolution [0...9]
# 0 = auto, 1 = 800x600, 2 = 1024x768
# 3 = 1152x864, 4 = 1280x960, 5 = 1280x1024
# 6 = 1360x768, 7 = 1400x1050, 8 = 1440x900, 9=1680x1050
