When I want to copy a file to a folder in the sidebar of the finder, I drag the file to this sidebar icon, the folder springloads (so far so good) and I drop the file into this folder, the file doesn't copy at all. The finder window changes back to the location the file came from. There's no feedback that the file was not copied. In my eyes, this is a rather risky behaviour of the leopard finder. It works the way it should when I keep the cursor on the sidbar icon. The bug only appears when I move the cursor to the opening folder. Can anyone reproduce that?
