Thanks very much for the help. That almost did it. The linewidth of the standalone line segments changed, but not the linewidth of the line segments in the shapes (mostly rectangles). I tried adding "Cline Segs" and "Other Segs" to the filter in addition to "Lines" and "Shapes", but it keeps showing this error:
"Shape line width cannot be changed."
I verified that the class of the shape is Package Geometry and the subclass is Silkscreen, just as with the standalone line segments.
When I do a "i" on a standalone line segment, a "width" property appears in the information. When I do a "i" on the shape, it also has a "width" property on all of its segments. So if it bothers to list the width of them, I think there must be a way of changing it.
I'll keep hunting around in the menus. Maybe there is a global shape linewidth setting.
BTW, when I add a line, it gives me the option of specifying its width. When I add a rectangle it only gives me the option of changing the "line font" (ie: solid, hidden, etc.).
