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

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@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
