I open two Yummy windows that are browsing different directories on the same remote server. When I initiate a copy from one window to the other via Alt-drag, Yummy doesn't report that some of the files (for example, "sourcefile")already exist in the target directory and ask me what I want to do, it simply creates files such as "sourcefile copy" in the target directory. In my preferences, all of the fields that deal with how to handle existing files are set to "Ask me". Am I missing the preference that would allow me to replace existing files in a situation like this?
