That tends to slow down a 750 a lot. Also, in pre-UniPress releases, the window optimization code gave up on anything harder than one-line or one-window optimizations. #264 Emacs has Gosling's fixedpoint code in display.c and his new fancier window optimizations, which handle cursor up&down motions (as long as lines don't wrap) as well as left&right motions. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci (301) 454-7690 UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
