I grab the file from my Windows Desktop, and I drop it in the remote file panel area (not the tree area though) of the explorer view. The transfer appears to be succesful, but I have to click refresh to get it to display.
I have changed a lot of settings, for example, double-click copies to desktop, background transfers on, etc, so I am attaching my wincsp.ini file:
