I'm not sure if this is a problem, or if I'm doing something wrong, but I can save/load individual just fine, yet when I try to open levels to a chapter (where it opens the library window), it never finds my levels when I search them. Anyone else having this problem?

On my laptop, the touch pad scroll wheel does seem to work on ordinary windows, but when I try to use it on the level editor it does not scroll through any of the objects. Does anyone know if there is a setting I can change that will fix this or if there is another way to scroll through the objects?
