Thanks guys, we'll get the issues fixed. For what it's worth, the RAM cache setting only applies to LaunchBox and isn't used in Big Box.
It took quite a bit of testing but I did just run into an issue...not sure if it's related or not. Got a message box saying I don't have write permissions to the LaunchBox folder, which obviously isn't true.
Can you guys test to see if this is only happening while images are popping in/caching? I expect that it's most likely happening while it's building the cache. Do the issues go away after the cache is completely built?
If blank images are coming up, that should mean that it's building the cache. However, they shouldn't randomly disappear either. Are you guys 100% certain that images are disappearing when they shouldn't be?
