AutoCAD 2010 :: Display Dimensions In Properties Box

I'm trying to figure out two things that have changed:

1) Lets say i create a polyline, lets say its 15 inches long. I used to be able to click on it and have the length show up in my properties. it no longer does that.

2) Lets say i create a polyline, it's green and has a dot pattern. I decided i wanted to change it to yellow and hidden pattern. I can no longer select the line and change it under the properties, it will change it in properties, but not on my screen. then when i draw a new line it will be yellow and hidden. I end up having to matchprop to make it work.
