Disappearing Scrollbars on the Visual Editor

I'm not sure it has anything to do with the visual tutorial. Only that the problem started to show up around the same time I created pages to show to visual tutorials.

What's happening now is if I have a post of six or 700 words. I can't scroll up in the visual editor to reach the editing tools.

I have to use this scroll bars for the whole post. It appears to be three or four pages deep before I am able to view by SCO and tags programs.

Any thought on this!

I uninstalled the visual lessons and all posts that had anything to do with them. No change
