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

I have observed this behaviour in Jove too. [Lines appearing blank on the display] I have not managed to identify any particular pattern to what causes it, but it is purely a display problem. If you move to the apparently blank line and then press END (or ^E) the cursor inded moves to the appropriate part of the screen. My usual technique to work round this bug is to do a succession of insert and delete characters, and then move the offending line off the screen and back on to the screenm. This usually causes it to become visible. I have seen the line suddenly blank when I have deleted or inserted a character, but I can't reproduce the behaviour. -- Peter King, Computer Science Department JANET: pjbk@uk.ac.hw.cs Heriot-Watt University ARPA: pjbk@cs.hw.ac.uk 79 Grassmarket, Edinburgh EH1 2HJ or pjbk%cs.hw.ac.uk@ucl-cs Phone: (+44) 31 225 6465 Ext. 555 UUCP: ..!ukc!cs.hw.ac.uk!pjbk
