Are you running ./configure as:

 ./configure --with-locale=ko

./configure can't see the LANG environment variable, so need
to use the --with-locale option.

This seems to be a bug in HanIM. (You can trigger it by modifying
the example programs that come with HanIM - in overspot.c, change:

    if (XFilterEvent(&event, None) == True)
to
    if (XFilterEvent(&event, window) == True)
)

If you just make the change to gdk_event_get(), you'll notice
that things work a bit strange. You can only type hangul in the
entry when the cursor is directly over the entry. Otherwise
you'll enter roman characters. I think this can be worked
around by modifiying GTK to use XNFocusWindow for the toplevel
window.

But there is also another bug. Over-the-spot entry doesn't work at all
in GTK with HanIM. To enter any Korean text, you need to run the GTK+
program as

 program --xim-preedit nothing

So that it uses the root-window preedit style. I don't know what is
causing this problem.

Well, it is not you. I can't figure out what GTK could be doing
wrong. (And the IM support works fine with Japanese input methods).
But there probably is a bug somewhere in GTK.

Better than my Korean ;-) 

Thanks for the report. I hope we get this working soon.
