I applied Alan Cox's patches to bogl-0.1.12 and found that bogl-bterm-udeb's bterm scrolled much faster. I have forwarded the patches to Daniel Jacobowitz. Anyone else who wants them, let me know.
It's probably worth checking Red Hat's sources in case there are any other improvements in there. The latest Red Hat version I found was bogl-0.1.9-26.src.rpm. Can anyone tell me how to get at the contents of a src.rpm? Edmund
