I found that the above is not enough. It seems that the display engine doesn't issue select-frame; i.e. provided that there are two frames A and B, there is a case that the display engine redisplays A while the selected frame is B. It means that even if we make such variables frame local that affect the redisplaying (font-selection, etc), any frame local bindings are just ignored. Gerd, do you remember this matter? Is my analysis correct? --- Ken'ichi HANDA handa@m17n.org
