Xline command no longer works in 2012

I used to be able to create an xline simply by activating the command, and then picking two points through which I wanted the xline to pass through (for xlines that I do not want constrained to ortho).

Since the install of 2012, I activate the command, pick the first point, but no matter where I pick, the second point is ALWAYS *Invalid*.  It doesn't matter where I pick.  I can thrash and click all over the drawing and never find a valid second point for the xline to adhere to.

What changed in 2012's Xline command?   And what am I doing wrong?

Thanks,

Pete
