Stuck in outline view

I run a school lab with a few users on each machine. One students came up with a problem. She is always in outline view, even when the outline button in the layers panels is not punched. When I log in to the same machine, I do not have the problem. I assume the problem is in the user preferences file. We are on Windows 7. I went into AppData and deleted what I thought was the preferences file, but it continues to return. Anyone have any ideas why I can’t get her out of outline view? Adobe Flash CS5
