I'm still discovering new, cool features in the Stackz - Dictionary Edition. When I'm in the edit dialog (select some stacks and press F2 or choose edit from the context menu), I selected an entry which was written in Hiragana and pressed F5 (same with right click - Convert to Kanji) - magic - there is a small window with kanji propositions (each with translation) popping up. This is wonderful! When I pressed F5 while having another word (or the same) selected, Stackz crashed - Windows error report dialog. It is perfectly reproducible, I rebooted and restarted Stackz several times. The first time it works great, the second time it crashes. If I close the edit dialog after the first time and reopen it with the same (or other) cards I can again look up one kanji, it crashes when pressing F5 the second time (immediately, the small window doesn't get visible).
I hope you can sort this out, it would be such a great feature! I really love Stackz!
