[Newbies] Why mouseDown only called for the first morph?

[Clemens Eisserer]

Hi,

I am new to Squeak and I try to write a tic-tac-toe like game.

I have a BorderedMorpth as board to which I add some EllipseMorphs as childs:

> for: 1 to : ...... [
> child := OwnEllipseMoph new.
> bordered addMoprh: child.
> child bounds: xPos at yPos corner: (xPos+fieldSize-5)@(yPos+fieldSize-5). ]

The result looks like the following image: http://93.83.133.214/morph.png
All the EllipseMorphs are identical and change their color at mouseDown:

> handlesMouseDown: evt
> ^ true

> mouseDown: evt
>	self color: Color green.
>	^true

The problem is that I only receive mouseDown on the first EllipseMorph I add.
When I click on the other EllipseMorphs nothing happens.

Any idea what the problem could be? Could it be the bound-setting
confuses Morph's event handling?

Thank you in advance, Clemens
