I've just noticed a problem with JOVE 4.14 (MS-DOS version). I was looking at some ASCII data files, and noticed to my dismay that they seemed to contain some blank lines, with a record missing at each blank line. However, using another program to view the same files, I was relieved to find that there were in reality no blank lines at all, and all the data were there. It seems to occur on or around line numbers which are a multiple of 826 (I noticed 826 and 1653, but also 216 at one point), and is something of a problem. I didn't try saving the files to see if they would be saved with a missing line, but it's disconcerting not to be able to see all of your file on the screen, even if it doesn't actually get lost. Has anyone else noticed this behavior, and (even better) is there a fix for it? Richard Stanton pstanton@gsb-what.stanford.edu

It's an old, old bug in the screen update function of Jove. It's been there for years, and is specified in one of the README files with the sources as a known bug with no known fix. If you can figure out what's going on there, more power to you! The problem is only with screen output, the line is actually there in memory. If you position the cursor on the missing line, and do C-A and C-E a few times, you'll see that the line seems to start in column 2 (!) and consist of blanks. To get the screen right, do C-A Backspace Return (deleting the newline in front of the offending line and reinserting it). I spent several hours once looking for this one, but had no luck... -tih -- Tom Ivar Helbekkmo, NHH, Bergen, Norway.
