• When searches are performed on an open dictionary, and an output list dialog is closed, the copy, move, delete and export menu items should be disabled.

v3.0.5

• In normal mode, the word type prompt rectangle was not printed in the correct position during exercises.

v3.0.4

v3.0.2
• The Weekly Reset day value has been aligned internally to match the Mac OS Date/Time function.

v3.0.1
• Some dialog messages have been enhanced to improve clarity.

v3.0
• Initial release

v2.0.6
• The Help system has been updated.

v2.0.5
• Adding new Kanji readings can cause a system lockup. To workaround this bug, do not add additional Kanji readings.
• Corresponding internal exercise information was not set up correctly after the status of a word was changed via the Edit word dialog. To workaround this problem, change word status only through the dictionary list search output.

v2.0.4
• When the Kanji exercise option was set to "Display all", the exercise sequencer displayed Kana at the same time as Kanji. To workaround this bug, the Kanji exercise option was set to "Hide unknown" and all Kanji were enabled.

v2.0.3
•Running JWM under the original Quickdraw caused an unimplemented trap error - the presence of Color Quickdraw is now detected at launch and unimplemented traps are bypassed. JWM now operates properly on older Macs with the original Quickdraw and System 6.0.7, though System 7 is recommended.

v2.0.2
• entering a teacher password for the first time in the MultiUser Edition sometimes caused a fatal error.
• changing the time when an unregistered version of JWM was running caused a 60 hour timeout at the next launch. No problem occurred for registered users.

v2.0.1
•Kanji could be attached only in a set left-to-right sequence.
• if the "Play introductory music" option was enabled for a student user of the MultiUser Edition, the music did not play.

v2.0
• Initial release
