When a modal dialogue appears and disappears, user inputs some char. string to text field.
The 1st char. of the string can not be input. That seems discarded.
The same instruction is mentioned the windows which shows up when the test program is invoked.
1) Invoke the attached test program
2) Press "TAB" key
A dialogue with "ok" button will show up.
3) Click the "ok"
The dialogue disappears and focus moves to the text field in the window.
4) Type "abc" You will see only "bc" in the text field.
