Importing files written with SWP 4.0

[Piero Pasotti]

Hi,
  I'm a newcomer to the Lyx's world. Unfortunately I have the need to
frequently exchange .tex files with people working with Scientific
Workplace 4.0. I'm facing some problembs both in exporting lyx files
to .tex and in importing swp .tex files to Lix.
  Could anybody suggest me a general solution to this problem? Does
exist any working translator from Tcilatex to Lix's Tex and viceversa?
