Indeed - Upon closer examination of that area I see that even the latest CVS version is having trouble with the geometry in that area, shorting some of it out to the plane. Replacing the co-linear lines with a single line appears to fix the problem. > I'd be curious to know how you drew that line, if you recall :) If you > have a lot of cvs revisions I'd also like to know if it got split at > some point along the way after the initial drawing. Oh - now you're asking _me_ to do some work. :) Unfortunately my CVS versions aren't fine-grained enough to catch how that happened. Knowing me though, I was editing a more complex set of lines and just straightened out a vertex. Thanks for looking into this in such detail - I'm learning a lot by trying to follow along...
