Using the .87 release on a Treo 600 I am finding several places in the ABC dictionary Pinyin display in the definition area where the letter 'e' is missing. For instance it will display mei as 'm i' and ze as 'z '.
I usually run in magnified mode (since small print Chinese books and dictionaries are slowly blinding me). In the smaller display mode all the e's are there, so this is a display bug, not a database bug.
