I've managed to get used to most of the new stuff in Lion, but the screwing with the File save stuff is just mind-bendingly awful, and has broken things as simple as trying to re-save a text-file or image from a read-only folder to a read/write folder.

Example: Choose a locked file and try saving a copy anywhere. Can you do it?

I've resorted to using the Finder to copy things into accessible places to work on them.
