rotate arrows in Lab

[mikemeister_admin]

This is certainly not a big deal, but in Lab the rotate arrows don't work quite like they do in the other modes. They stay in vertical mode even when moving horizontally for quite a bit longer.

I just went back in and adjusted the L curve, and then moved it back again. The arrow then went really squirrelly, and started changing orientation incorrectly all along the borders.

HSB is exactly the same.

Actually, I need to modify this again...it seems if I modify a curve by dragging the upper right corner towards the center a little, and then click and drag  the rotate tool around the border, it just starts flipping around in circles. It really hates that.

Yes - I just tried that .  It is trying to rotate the curve with just one end point selected.  Not a good thing at all!  I'll add some improvements tonight.
