I'm having a problem with anchor points in one document. In all my other documents, if I click on an path with the Direct Selection Tool, the anchor points and the control lines (is that the correct name?) become visible and I can alter the shape as needed. However, there is this one document in which if I click the path or an anchor point with the Direct Selection Tool, the anchor points and control lines do not show. They show if I click and drag the anchor point, but I cannot change the control lines because if I release the mouse button, the anchor points and control lines disappear. I suspect that I accidentally changed some setting through a keyboard short cut. What setting would cause this behavior? I'm using Illustrator from CS 3 (13.0.2) on an Intel Mac (running OS X 10.5.8).
Thank you in advance for any help you can give me
