Some versions of LW 4.0.x worked well for some & not others. I know myself I had problems connecting with one version but connected well with others. So .. if it comes to that, there is a post on these forums with links to some other LW 4.0.x versions.

I do still have LW 4.0.x on my old mac under OS 9. But haven't used that LW in probably well over a year.
