You're analysis was very good a gtk_adjustment_changed() just worked fine 
Thanks a lot ! 
You're in now in Amaya cvs log credits for that change.

2) Multikey charachters

I'll dig it immediatly !
( a lot of work have been done on the motif Amaya version to get it work, as 
all key combinations were in a table that we we're matching... my secret hope 
is that we can get rid of it !)

Sounds Very good !
(An Unicode amaya-I18n is also under way... 
so we're also following your work in Pango with much interest...)

3) Copy, Cut&paste directly in GTK instead of an actual X cut&paste :

We'll try to accomodate with it. GtkInvisible could be a way to escape from 
our architecture... we'll see !

Just let us finish our port from Motif to GTK, 
then to GTK win32, 
(if it's possible...),
and then,
we'll go on for the next version of GTK with pleasure !
And we're all sure our work will be a lot more convenient and cool, 
because of coding with only one, good, robust and clean API !

All thanks to gnome team !

Thanks a lot, Owen,
You save me a lot of time and headhaches !
