The control labeled Line Style appears to be replaced by the one called
Weight, and you are right that it has only weights. Moreover, if you click
on More Lines... to bring up the Format AutoShape dialog, I see what you
mean about Style being unavailable. Oddly, this is true only for lines: the
control is available for outlines of other shapes, including arcs. It is
possible to draw an "arc" that is pretty much straight, but that's not a
very helpful workaround.
