Reviewing patches doesn't help much unless you know exactly what you're looking for (I mainly do that to see when a change was made and what the corresponding log comments are). It's likely that it only appears "randomly" because the conditions for reproducing the bug are not well understood. Talking about something that appears when less is run (is this using xterm's alternate screen? Probably). The alternate screen buffer is only as large as the terminal window. The normal (with scrollback) is much larger. So bugs that hit a boundary are more likely to happen with the alternate screen buffer. (I don't use the alternate screen much, so it's mainly other people who would notice a problem with it). -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net
