So, the thumbnails are not being rebuilt? Because as you scroll through your game list, the thumbnails populate very, very slowly... as if they are being repeatedly created as you scroll games onto the screen. But you are saying this is because the optimization for displaying the images is poor? Just making sure I understand. Ultimately, I think for new users, especially, but for all users really, it is the same effect. The scrolling through game thumbnails is one of the main things you see when you are using LB, so it can lead a person to think that the software is slow, or "unoptimized", even though it's really just a thing with the thumbnails.
