he said me offline around 52000 chars , and you do not need to press
ok to trigger it, its supposed to occur when do you copy paste the
chars within the area, however here nothing happen on xp sp2 en +
firefox 1.5 , I can just see my AAA buffer replaced by a blank buffer
once I paste it in the box..
