My EUR 0.02: I don't know if these things still exist in the version Laurie is using, but in P98SEsp6 it is possible to have a zero-length segment of track. Invisible, even when selected, but they can still get selected by drawing a selection window or by global edits. They are usually -inadvertedly- created by moving an endpoint onto another endpoint of the same track. Lock and netname properties of these objects still apply, as may do other properties. After some testing I found that it is also possible to create nearly invisible (just one pixel wide at any zoom factor) arcs or strings, using zero or negative trackwidth. Also, adding the .Legend special string influences the place where your preview ends up on the page, depending on the number of different holes you use; even when the legend only displays on another page. Last but not(?) least it could have been a freak bit error that changed a coordinate into the negative realm, I found the program's behaviour then erratic at best...
