I think it is a bug from scim but related to qt because the same problem occurs with Qstardict. Gjiten has no such problem.
The status menu of maemocjk-him-scim-anthy also changes its position by itself ad I cannot make it return to where it should stay. This happens when I install something else, but can't remember which, so can't tell what it conflicts with.
If this scim anthy thing works like Atok or IME on windows it 'll be perfect.
I think the creator of this nice input module well awares of the problems but seems he is so preoccupied with Meego to fix them
