I don't think they addressed the situation in which you attempt to copy or cut files you don't have read/write rights too, what happens then? You should certainly be allowed to select them. IIRC this is an annoyance in MS Windows (up to Vista, I've not used MS Win7) where you don't find if a cut/copy action has failed until you actually paste the files.<p>If you cut/copy to a "shelf" as in a suggestion in the posted bug report that could solve the above but you are adding an extra cut-paste to all such file operations then.<p>Just mirroring whatever OSX and Vista/Win7 do is probably the best unless you want to overhaul your whole UI.
