Created a 3 zone project. Zone 1 video and live video. Zone 2 and 3 are jpeg images.
Zone properties set to Scale and Fill.
Presentation worked well initially.
After selecting the jpeg images to be cached, all images were scale up by a factor of about 4.
The effect was only the top right hand corner of the jpegs were visible.
Un-selecting the cache restored the presentation properties.
Was hoping to use the cached images for a flashing sign.
