What this patch is effective for:
---------------------------------

    This patch is provided mainly to avoid the problem reported in 1132141
    that atok7 dumps core on accessing a corrupted dictionary.

    In addition, this patch changes some behaviors of atok7 or ATOK7 dictionary
    maintenance tools as follows:

    - To start ATOK7 dictionary maintenance tools, it has been needed that
      "/usr/openwin/lib" is set in the environment variable LD_LIBRARY_PATH
      (1130017). By installing this patch, you can start the tools without
      such setting.

    - To start ATOK7 dictionary maintenance tools, it has been needed that
      DisplayLang locale is either "ja" or "japanese". By installing this
      patch, the restriction is removed. However, it is not supported to use
      the tools in the environment that DisplayLang is not set or it is set
      as non-Japanese locale.

    - The problems reported in 1129536 and 1129537 are solved.

    - The scroll direction by pressing PgUp or PgDn key in show popup
      (KOUHO ICHIRAN by double SPACEs) has been inconsistent with the
      description in ATOK7 User's Guide (1130948). By installing this
      patch, the scroll direction is corrected by the document.

    - The problem reported in 1139190 are solved.

    - The problem that atok7 does not accept any requests after once
      converting and committing a reading if using a user dictionary
      corrupted by converting and commiting the reading (1142786) is
      solved. 

    - The problem that the following functionarities of atok7udictool
	(1) Listing Entries (Ichiran-Hyoji)
	(2) Reorganizing a Dictionary (Naiyou-Seiri)
	(3) Merging Dictionaries (Jisho-Merge)
      fall into an infinite loop if using a user dictionary corrupted
      by converting and commiting the reading reported in 1142786
      (1142787) is solved.

    - The problem reported in 1138053 is solved.

    - The problem reported in 1121634 can be solved by adding the following
      resource in resources file,

        *xci*atok7.config.PREREAD:    0x1

      where the value 0x1 means that atok7 do not pre-read dictionary.
 
    - The problems reported in 1143828 and 1144286 are solved.
