Previously xcin-2.5.2-preX worked fine on my system. I had upgrade XFree86 to 4.0 then downgrade to 3.3.6, then compile libtabe-0.1.8 and xcin-2.5.2, but when i press ctrl-space to toggle input method in rxvt, xcin doesn't response. And the "testprog" said "Unprited char." when ctrl-space pressed. Xemacs show a warn message "X input method open failed" at startup. My locale is zh_CN.GB2312. Any suggestion? Thanks very much!
