- Your window manager crashes.

  If you use nearly all the colormap (for example, you have a color
  background image), jetset will try to use a private colormap.  But
  tvtwm (and maybe other window managers) may crash if it has to switch
  between two colormaps in the same toplevel window.  I have included a
  patch for tvtwm pl7 that fixes this (I just looked how it was
  corrected in ctwm).  The other solution is to use another window
  manager, there are plenty of them.
