one machine i thought might have had a problem with silverlight 4 beta.
but now at work on xp pro sp3 and silverlight v3 the same problem is happening.
not sure if this relates to the issue but the player starts with the controls half way up from the bottom and drops down.
plays in the small vew ok.
click on fullscreen and nothing. small player is now a black box - no controls no video no picture.
no fullscreen mode.
reload page and all is ok but fullscreen not working.
tried the halo video and the visual studio father of vb on front page and they both do this.
not yet tried older videos.
