    Hi Leon,

    I don't think it is a very good idea to use a list widgetto display more
    than a few hundreds of line. There should be some reasons for that :

        * user may have to scroll during four hours to find the thing he
wants
        * if the entry are sorted, finding stuff is easier but the insertion
of
        items is very slow (something like O(n^2) if I remember the last
        discussion about GList sorting here). That's probably why your
        application is so slow when you use 50000 words (up to
        2 500 000 000 operations ! whow !)

    A better solution should be to use some kind of pre-sorting (A, B, C,
...
    should do it well, since it will reduce most of your list to handle
something
    like 2000/3000 words - that's really a big list :)

    Hope it helps,

    Emmanuel
