	If you turn snap-to-grid on, then you can line up the vertex end  
points together (and keep the others in line). Then you can turn that  
off, use the geometry inspector to make each line the same length  
(reposition them if they get out of wack... in OG 4 the alignment  
guides help for lines, I don't have OG 3 on my system to try that),  
and then, as a last step, join the vertex together (that won't alter  
the other end points. Or you can group the two lines, then work with  
them as a shape.
	I do agree that you should be able edit the lengths of the lines if  
both endpoints are not connected to something.
