I am having a strange problem where any mail documents that I have open in preview are unreadable. The preview pane opens to its normal size and I can see the header info just fine. The weird part is that the body will not display more than a single line. There is a small scroll bar that will let me look at the body one line at a time. I’ve tried moving the preview pane to either the side or the bottom of the window but it makes no difference. If I open the mail document by double clicking on it it display fine, just the preview is broken. I’m attaching a screen shot of the problem as well. Any ideas?
