can't see pencil path

I can't see the pencil path. I use the pencil a lot to edit existing paths. I've never had an issue before. The existing path would remain highlighted while I edit it, and I would be able to see the path that I was drawing with the pencil. Worked great. Now I can only see the highlighted path that I want to edit, but I can't see the path of the pencil as I draw. I can still edit paths this way, but it makes it more difficult because the highlighted guides all disappear when I start to use the pencil, and I can't see exactly where I'm drawing. It is set to "show edges". I have turned smart guides on and off. I have reset my preferences and even uninstalled and reinstalled illustrator to no avail. Thank you for any help.
