Your cursor fix.. fixed it
.. Including a mini problem my system has had for many versions.. (which I kind of thought as normal behavior). When first started my cursor would stay as an hour glass until I moved it out of the window... now fixed.
But.. perhaps the "grab" hot spots could be a few pixels wider, possibly some shaky hands might have trouble staying on the line to grab and move.
And.. I like the extra options you added to the right mouse click
