Do > you _ever_ see a cursor in non-selected windows on this system? > No (AFAICT). Note: This might (or might not) be a different unrelated problem. I've just realized that this is true for my Emacs 23.3 also. Also, as noted, changing cursor configuration (e.g., "blinking cursor") has no apparent effect. If others using Windows 7 do see an empty rectangle in non-selected windows and/or are able to change the cursor config from within Emacs, then obviously there's something special/different about my configuration. --------------------------------------- >> abc >> 123 >> | >> >> >> Strange .... > > Probably because of the different dimensions of the letters and the > digits. > > If you go to one of the 'a' characters and type "C-u C-x =", what font > does Emacs show as being used for this character?

Only happens some fraction of the time (i.e. not on every down-arrow past the end of the buffer). Seems definitely dependent upon the contents of the buffer. I even got a fail (artifacts) once (even with scroll-conservatively set to 0) with a 24 line screen and a buffer of 50 lines of 'abc' and just repeatedly doing M-S-< followed by M-S-> . --------------------------- My comment: maybe let this simmer for a while and see if anyone else reports a similar issue (or eventually decide the issue is something about my system). (It's not the end of the world for me to run emacs with 'scroll-conservatively= 0') Bill
