The double page mode does nothing when the images are more square than rectangle.
It has been mentioned many times on this forum, but this behaviour is NOT YET fixed in the new version!viewtopic.php?f=5&t=633viewtopic.php?f=8&t=702
I've waiting for the fix for a long time already and moved on to another reader for this exact reason, but they are not as good as CDisplayEx...
I beg you please fix this!! Just disable the "rectangle-ness" detection because it's not needed for manga readers.
I hope I don't sound too "pushy" but I am really desperate for a fix..
