Hi, I'm Nghia.
I'm starting to translate Moodle language pack after a long holiday, but I realize that there was a really slow annoyed delay when I started to type text in AMOS translation box. Whenever I type, it took a few (micro)seconds delay to update the text. Any translation box (row)caused the same!
I think there was something got along inside whenever I type.
Please check it, now I have to type the translation in a text editor and copy back to the box.
I typed in my browser: Google Chrome 45, Firfox 40.
