I have a Macbook Pro 13" connected to an external monitor with an extended Desktop running a Windows 8.1 PDVM. When I try to drag a file from one monitor to another, either from desktop to desktop, or from a folder to an email, or any other situation, when the mouse moves to the other monitor, the mouse cursor changes to a picture of a folder, and when I release the mouse button, nothing happens. It seems like PD thinks I'm trying to copy the file to the MacOS desktop, because if I have MacOS on one monitor and Windows on the other, the same behavior happens and the file is copied to the mac desktop. But I want it to stay in Windows. Is this a bug or a setting? It worked perfectly in PD9.
