I'm having a little problem with folder formats / view modes.
Basically, if I'm inside a folder and I change to thumbnail view, or change the file sorting method, and then navigate to another folder, that folder will also be shown exactly like the previous one. I have a custom format set up but it doesn't seem to help in this case.
If you hover your mouse over the little padlock at the bottom of your lister you will see where the current format comes from. Is it possible that you have locked the original folder format? If so, that would explain things. In my sample you can see that the format is unlocked (padlock is open).
It's unlocked and the format comes from Default. I tried locking it and it behaves the same when navigating to other folders (using the same lister/pane - if I open a folder in dual or a new lister it behaves properly).
