SWT: Buttons in ToolBar: always focused

Hi, I'm working on a GUI application with SWT and I've got a problem with buttons in a toolbar.

This is the part that defines the ToolBar:

// Tool Bar
mainTB = new ToolBar(shell, SWT.SHADOW_OUT | SWT.WRAP);
//mainTB.setLocation(3, 3);

ToolItem connectB = new ToolItem(mainTB, SWT.FLAT | SWT.NO_FOCUS);
connectB.setImage(new Image(display, Start.class.getResourceAsStream("/images/JB_logo_24x24.ico")));
connectB.setToolTipText("Connect to JustBase.FM");
        
new ToolItem(mainTB, SWT.SEPARATOR);

ToolItem optionsB = new ToolItem(mainTB, SWT.FLAT | SWT.NO_FOCUS);
optionsB.setImage(new Image(display, Start.class.getResourceAsStream("/images/JB_logo_24x24.ico")));

        
ToolItem asd = new ToolItem(mainTB, SWT.FLAT | SWT.TRAVERSE_NONE);
asd.setImage(new Image(display, Start.class.getResourceAsStream("/images/JB_logo_24x24.ico")));

mainTB.pack();
        

        
shell.addListener(SWT.Resize, new Listener() {
    public void handleEvent(Event event) {
        Rectangle clientArea = shell.getClientArea();
         mainTB.setSize(mainTB.computeSize(clientArea.width, SWT.DEFAULT));
    }
});

What happens is, that the first Button of the toolbar, is always focused. Ican switch the focus to another Button with the arrow keys or with Tab, but I can never get rid of the focus.

Is it possible to make those buttons unfocusable?

And another thing: I've set my ToolBar to wrap around "new ToolBar(shell, SWT.SHADOW_OUT | SWT.WRAP)", but it doesn't do that.
When I make the window smaller that the width of the ToolBar, it simply hides behind the edge of the Window.

Aaand another one: As you can see, I'm using a SWT.SEPARATOR between the first and second button.
Is it possible to change the space between a buttong and the separator?
In Web development terms this would be "padding".

Cheers, and thanks in advance,
