Hi, this has been driving me crazy. 

forward-char on vt100 w. emacs v. 21.3.1on linux (RAS 2.1) 

Every 7 or 8 forward-chars in emacs results in the next 4 characters of text being blanked out. I can work around by redisplaying the screen by typing ctrl-l but that gets tedious. I think this may have something to do with tab-stops which also have about the same periodicity and the bad behaviour occurs only on columns whose number is one less than a multiple of 8 (i.e. 7, 15, 23) . When I put my terminal emulator in display-controls mode I see that what is output is 4 blankspaces followed by a backspace. This behaviour does not manifest in any other character cell application (e.g. vi) It also expresses the same way using other terminal emulators. 


Please help - I can't stand vi but see no good alternative.

Best.

-Allen
