I've experienced this issue in both the regular and 64-bit versions of the CK so I guess it applies to both.

I'm really confounded by how it works with regards to remembering what subfolder you were in, when you are successively adding multiple files to a list, like you can with sound descriptors. Sometimes when running the CK, it seems to remember and make your life easier, but more often than not it just returns me to the root/data folder and I have to do the whole process again. This is insanely annoying when I'm dealing with stuff that requires me to add a lot of sounds into one sound descriptor, since for whatever reason they chose not to add functionality for selecting and adding multiple files in one go.

And I can't seem to notice any pattern or reason behind this inconsistent behavior. Does anyone have any experience at all with solving or controling this?
