[GRASS-dev] r.le--after some fixes still needs work

[Hamish]

Oh & by the way, the reason that r.le.setup was hanging on this call:

  G_system("d.frame -e")


was probably because the graphics driver was open when that call was
made, and d.frame can't run until the graphics driver is closed
again. So d.frame was both waiting for the driver to close and halting
r.le.setup in the middle, so the driver couldn't close.
