Bug: Scrolling Numbers

Hi David,

At first I thought it was me going the wrong way each time, but I have finely narrowed it down to a glitch in the matrix... well UI

When I go to set the Slider minimum as -10.0 I get hold of the tens and drag it down (contrary to my brain) so that I get a minus number. Then when I think it is sufficiently far enough down I release and the minimum sets to +10.0 and the Max moves to +11.0. I have noticed that (see picture) even with the minutest gap under the 1 (before the range increases to 20.0 the minimum fails to be set correctly

Also While this picture is here can we have 0 set as the Extend Curve's defaults please.

Normally I want to extend/shrink one end and have to go into L1 as well to set 0
