kCamLibCtrlPreviewStop Stops the camera preview mode for images. Does not erase the preview rectangle content.

On the Zire71, when I stop the preview using kCamLibCtrlPreviewStop, the last viewed image stays on the screen. On the Zire 72, the preview area is ereased (becomes white).
Anyone noticed that???
The Zire 72 uses an overlay mechanism to directly map memory filled by the camera sensor over part of the screen -- the LCD controller can fetch a rectangle of the screen from a different part of memory, avoiding the need to double-buffering. When the camera is disabled, this overlay is turned off, and you're left with what was under the overlay to start.
