I've created a swf file with Tiltviewer embedded on the left and a FLV video (stopped) on the right. There is no overlap.

With the video in place, mouse clicks for the Tiltviewer images seem to stall and generally become unresponsive. It takes a lot of clicking to get Tiltviewer to respond. The video plays normally, however.

If the video is removed, Tiltviewer responds normally.

Any advice on how to fix this?
