I just upgraded to Flash CS6 yesterday, and am trying to work on an animation project.
Whenever I use the Select Tool to modify the edges of a Paintbrush stroke, or a Pencil line, ALL of the lines in the image are highlighted as I bend the edge this way and that.
I'd prefer for the outline highlight to only show up on the area I'm actually modifying.
I find this default behavior really distracting, and I can't figure out how to turn it off.
If you are using normal mergable shape mode,curves when selected has dotted grid pattern to indicate the selection.However if all the lines are getting selected that means they are all connected.Switch to subselection tool and see if all the lines are connected. In case you dont want different lines to merge on intersection then use object drawing mode.However if you you want to continue with normal shape mode and want only outlines to be displayed,you can choose View>Preview modes>Outlines(CTRL+SHIFT+ALT+O on WIN/CMD+SHIFT+OPT+O on MAC)).Hope this hhelps
