Hi,
I'd like to report an issue with picture box control and silverlight SDK(6.3.11 version). When you play with the visible property of this control, the screen doesn't refresh automatically : you need to press F5 button to force the navigator to refresh. You can reproduce this issue by adding one button and a picturebox to a form. The action associated to the button changes alternately the visible property of the picturebox control.
Regards
