Hi,

I want to make some buttons in a HBox the same width. Each button should always be as wide as the widest button.

I overrode layoutChildren to do that. Usually it works the way I want to.

But under certan circumstances it doesn't.

In this example I have the HBox in a BorderPane at the bottom. If the Button at the center is wider then the three buttons at the bottom my logic applies only if I mouseover one of the three buttons.
Although layoutChildren is called with the correct width.

If the center button is very small, it works as expected.

This is some strange inconsistent behavior. A bug?
(using 2.1 b08)
