Just getting ways explains why it is that segments that have been
created with no way don't show up.
Another problem that I have is when you try to extend a way or join 2
ways up. Examples include: continuing to map a way that was only
partly done previously; and adding an alley footpath between 2
These problems make it difficult for me to use potlatch, and I prefer
to use the applet for editing which requires the yahoo imagery, until
they are resolved.
