Thanks! That's a very strange phenomenon. But, I can't reproduce it. When I hit PageDown four times, the top line is "Luxi Sans:style=Regular", and "Corsivo" appears on the 9th line (logically 8th line because of continuation). In my case, this font is selected for the default case: -bitstream-Bitstream Vera Sans Mono-normal-normal-normal-*-16-*-*-*-m-0-iso10646-1 Which font is selected in your case? And, what does "Emacs begins looping while in redisplay" exactly mean? --- Kenichi Handa handa@ni.aist.go.jp
