Input field loses focus

Hello,
Goldendict is a very nice program, but one thing annoys me very much.
You:
1) enter new word in the input field;
2) press Enter;
3) press Alt-S in order to hear sound of the word again;
4) switch to another application by Alt-Tab;
5) switch back and trying to input a new word, but...
it doesn't work. The input focus is in the menu at this moment. You type a few first characters and one of the submenus opens. If you type fast, you can even select one of the items in the menu. Then you realise what is going on and press Esc one or few times and try to type in your new word again. The same thing happens again because the input focus still in the menu.
This behaviour annoys me very much because at this moment I have to grab the mouse and click into the input field.
I think it would be great if after switching into the application you can type in words straight away.
Ubuntu 9.04, Qt 4.5.0
The latest build from Git, but this behaviour was few months ago too.
