Return focus to main window

Hi all,

Im building a GUI using appdesigner, there are check boxes that can be controled via keybored (0-3) and by mouse also, plus some bottuns.

Every time I use the mouse to click one of the check boxes or buttons the focus goes there and the program doesnt receive keybored input anymore until I click back at the background of the GUI.

I trued varius things such as Figure(app.UIFigure) and to use drawnow, nothing works. Im about to try writing a script in java that moves the mouse a bit and clicks it but it seems an off idea, too much going around the problem and not solving it.

Does anyone have an idea on how to solve it?
