Isolating/manipulating joined arcs in Flash

Question

In illustrator when using the pen tool and drawing
arcs/curves, you may connect a series of curves and manipulate
individual curves without affecting the ajdoining curve. I
accomplish this by drawing curve #1 , selecting the end anchor
point of that curve, press the option button, then drag a new curve
using that end anchor point as the beginning point of the new
attached arc or curve. All the preceding arcs are attached as a
single object but I can manipulate each arc individually. How is
this accomplished in Flash? If I attempt this in Flash I get the
change direction icon and I lose one of the 2 handles on the
previous curve!

Answer 1

As kglad said, pay attention to the 4th frame in a button. There are 4 frames. First is the "off" state, second the "mouse over" state, third the "mouse being pressed" state and lastly the "hitarea". For each of these frames (states) it's up to you to put the right graphics in, if you wish to use buttons.
The 4th frame of a button (or again, the "hitarea") is where you want to place an object that covers the area where you want the button to be triggered when your mouse enters it. That's the frame (in each separate button) you want to draw an outline of each region. You do not put the stroke in that frame or it will be considered a valid "hitarea" and when you roll over the stroke it will trigger the button. Right-click in that frame in the timeline and "insert a blank keyframe" to remove the stroke from it and then draw your region in that 4th frame. So keep your "hitarea" frame to just the area you want to trigger the button.
Once the button is triggered via rolling inside the "hitarea" you defined above, it will show whatever you put in frame #2 or a button (the "mouse over" state). That's where you want to put a stroke that's highlighted in some way to indicate to the user the stroke is assigned to that region.
