Done, I have just tested GTK2 in Windows (XP). The letter duplication 
doesn't happen. If I type an accent (a dead key) in one control, and 
move the focus to other control, the first "loses" the accent. It's a 
good behavior (to me). I made the change in gtk2proc.inc and the 
behavior remains the same.

In Linux, with the original gtk2proc.inc, I have the letter duplication 
problem. Changing the gtk2 binding code, I can type accents fine. But, 
if I type a dead key in one control and move to other, the accent 
"stays" in the first control, waiting for the letter. I don't see it as 
a big problem.

The changes I made:
- Remove the CheckDeadKey procedure
- Replace its call by a: *gtk_im_context_filter_keypress(im_context, 
AEvent);**
