I report the additional facts about this problem. In my environment, uim is used.
1. This also happen with ascii characters. This is not only for Japanese characters. 2. It seems that whenever this symptom happens, the dropdown list for suggestion is appearing. 3. Similar symptom also happens for a text box in a page, but it is very rare. The probability to freeze is much higher in the search toolbox. Anyway, I haven't found a concrete procedure to reproduce it for the both. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (990, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.18-4-xen-amd64 (SMP w/2 CPU cores) Locale: LANG=ja_JP.UTF-8, LC_CTYPE=ja_JP.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages uim-xim depends on: ii libatk1.0-0 1.18.0-2 The ATK accessibility toolkit ii libc6 2.6.1-1 GNU C Library: Shared libraries ii libcairo2 1.4.10-1+b2 The Cairo 2D vector graphics libra ii libfontconfig1 2.4.2-1.2 generic font configuration library ii libfreetype6 2.3.5-1+b1 FreeType 2 font engine, shared lib ii libgcc1 1:4.2.1-4 GCC support library ii libgcroots0 0.7.5-1 GC shared library for a Scheme int ii libglib2.0-0 2.14.0-2 The GLib library of C routines ii libgtk2.0-0 2.10.13-1 The GTK+ graphical user interface ii libpango1.0-0 1.18.1-1 Layout and rendering of internatio ii libpng12-0 1.2.15~beta5-2 PNG library - runtime ii libstdc++6 4.2.1-4 The GNU Standard C++ Library v3 ii libuim5 1:1.4.1-5 Simple and flexible input method c ii libx11-6 2:1.0.3-7 X11 client-side library ii libxcursor1 1:1.1.9-1 X cursor management library ii libxext6 1:1.0.3-2 X11 miscellaneous extension librar ii libxfixes3 1:4.0.3-2 X11 miscellaneous 'fixes' extensio ii libxft2 2.1.12-2 FreeType-based font drawing librar ii libxi6 2:1.1.3-1 X11 Input extension library ii libxinerama1 1:1.0.2-1 X11 Xinerama extension library ii libxrandr2 2:1.2.1-1 X11 RandR extension library ii libxrender1 1:0.9.3-1 X Rendering Extension client libra ii uim-common 1:1.4.1-5 Common files for uim ii uim-utils 1:1.4.1-5 Utilities for uim ii zlib1g 1:1.2.3.3.dfsg-5 compression library - runtime uim-xim recommends no packages. -- no debconf information -- Kimikazu KATO <[EMAIL PROTECTED]> Nihon Unisys, Ltd.
