Most (if not all) of this behavior was fixed in xcircuit 3.7. The three
primary differences between version 3.6 and 3.7 are (1) the addition of
support for multiple windows in 3.7, (2) the correction of a lot of bad
behavior with editing paths, and (3) the addition of full support for
editing more than one element at the same time (3.6 has rudimentary
support for this, but only if all the elements selected are polygons.
For example, in version 3.7, you can generate a parallelogram,
then select the two points on any side, and move both exclusive of the
other points. Previously, this could only be done by changing the
"polygon edit mode", and it would only work on 4-sided figures.
Additionally, for example with the polygon-spline combination mentioned
above, with version 3.7 you can select the entire spline, and move it
away from the polygon without altering its shape. This is, of course,
a critically useful feature for stretching and reshaping things like
boxes with rounded corners.
I think the main problem here was my not promoting version 3.7 to a
stable release, after having fairly thoroughly debugged the element
editing changes and additions.
