Hit Testing in WPF

[moroshko]

Hi,
I have an Ellipse on a Canvas and I'm doing a Hit Testing on it.
Every time I click the stroke of the Ellipse, the test pass.
If I click in the middle of the Ellipse, the test fails.
This is good !
After I fill the ellipse like this: myEllipse.Fill = new SolidColorBrush(Colors.Blue);
the test pass also when I click in the middle of the Ellipse.
How can I disable this ?
(even when Ellipse is Filled, the test will fail when I click in the middle)
Thanks !
