f11 bug

Here is a bug when I use f11 to maximize the editing space. It has to do with the documents list. I have the regular folders (My Docs, Trash, etc), and also three more at the end that I have created.

Everthing works fine when I am in the default editing space. But if I do f11 and am in the top end of the file list, then the bottem folders disappear and I can't access them. So for instance if I am in My Docs and I have f11 on, then the lowest folder that shows up on the docs list is Public Docs, and I can't scroll down to the three folders I created that are below Public Docs.
