Drag and Drop Not Working

OK – drag and drop is not working on my Audacity 2.04

I’m using W7 64 – can anyone help with this?

Drag and drop of what exactly? If it is a file, please give the extension of the file (the three or four letters after the dot).

How are you dragging exactly, to the Audacity icon on the desktop, or into the Audacity window?

If you mean Audacity project files (AUP), you cannot drag and drop them into the Audacity window. You must open AUP files using File > Open in Audacity, or you can drag AUP files to the Audacity icon.
