DESCRIPTION:
On Motf AWT(MToolkit), I cannot input any character on multi window environment.
It seems focus related problem.
It's not related locale or XIM server.

Test instruction is as follows:
1. Compile and run following program
2. One of window may have input focus, type some characters
3. Move input focus to the other window by using mouse, type some characters but nothing happen
4. Move back input focus to the first window by using mouse, type some characters but also nothing happened
