I'm working with Ill. 10.0 on Windows XP. I am currently working on a path that keeps disappearing whenever I alter the anchor points. I have found that if you toggle the visibility off and then on again that the path will re-appear.

It didn't bother me at first, but now it is getting really annoying. Is there a command that I may have accidentally pressed to make this happen? What is the cause of this problem?

Any help would be great.

Thank you!
