Hi,
that looks like Android suddenly for no apparent reason applies some
weird top padding for the Japanese font on your device. Unfortunately it
works fine on my device, so fixing this won't be easy.
As a quick test, could you please try to check "Settings / Expert / Do
not use Japanese font" and restart Aedict? Also make sure you're not
using any custom Japanese fonts at "Settings / Expert / Custom Japanese
Font" and "Settings / Expert / Custom Japanese Font for large characters".
If that doesn't help, could you please post as much information as
possible about your device and Android version? With lots of luck I'll
be able to reproduce it in the Emulator; if not, I'll have to devise a
blind fix.
This Android fragmentation is horrible.
Best,
Martin
