I use ACDSee 3.1 because I prefer it to the newer versions. When I create a folder and try to drag images in to it, it doesn't move the files, its just creates shortcut files to the images in the destination directory. This doesn't occur in version 3.0. and I tried it with Windows Server 2003 with and without all Windows updates. Any idea what this is or how to fix it?
