Why does my shape change when I change stroke attribute?

Question

Hello,
I am having problems with my vector shapes automaticly changing shape (the position of every point that makes up the shape) when I increase the weight of the stroke or at color of the stroke. I hope that is clear.
For example: I have a Circle, then I change the weight of the stroke by clicking up on the arrows in the stroke dialog box. Every click up or down moves each point in a different direction. By the time I settle upon the weight I want, the shape is no longer a circle, but a abstract ameba shape.
Can anyone lend me some wisdom for what I can do to fix this problem?
Thanks a ton!

Answer 1

You select only part of the path instead of all of the path, that is some anchor points are selected, solid, as opposed to active but not selected outlined.
Option clickon the path withthe direct select tool or click on the center point to select the whole path with the direct selet tool or use the selection tool or drag a marquis with a selection tool to select the path and the anchor points
now you can move it with the arrow keys
oh I see you want to change the stroke weight you need to have the cursor active in the Stroke panels weight field in order for the weights to change so first select the path then click in the weight field of the panel.
