I asked this question a long time ago but it has been deleted from" my profile" When I want to select some photos at random in a folder by highlighting them.Sometimes they get copied and added to the folder.Any ideas please!!
That happened to me today - 3 times, so annoying. I have got round it by only highlighting max 4 photos at any one time. I do this often as I want to move photos from folder to folder - ending up with 4 copies is a real pain! I don't know why it does it, except that Copy is next to Cut on the drop-down... but if you only do a few at a time, it seems to work.
It's because you have accidentally moved the mouse while highlighting. Even a small movement will make the computer think that you want to drag and drop the files.
