This isn't the fault of the manual page documents themselves. I'm not sure exactly what *is* going wrong here; it's probably either a bug in the terminal emulator itself or a bug in the pager you're using. You should add information to this bug about what pager you're using (if you don't know, it's probably "less", but perhaps you changed it).

I have attached some example screenshots, so I ran 'man dpkg' and this is what it looked like initially dpkg_man_top1.png, but when I scrolled down to the bottom of the page and then back up again to the top, the top looked somewhat different as you can see: dpkg_man_top2.png. Now, it wouldn't matter where I had scrolled down to, nor where I had gone up to, the effect witnessed would have been the same. --- OS Information: No LSB modules are available.
