So, my two page spreads have been having a bit of a problem with CDisplay. I decided to check into this problem and discovered that CDisplay will not correctly display any image created in Photoshop with a transparent background.
To fix this, I've gone through each spread I've released and added white backgrounds. All of these should display properly in CDisplay. Just replace the old files with the new files from these:
Getter Robo Go CDisplay OK Spreads
UFO Robo Grendizer CDisplay OK Spreads
I'll avoid this problem in my future releases.
