annoying feature

When I drag and drop a file from the remote panel to the local panel, I have to drop it to a blank area in the local panel. Otherwise, an (executable) file in the local panel may be selected, and the remote file is downloaded to the temporary directory, and the executable is executed to process the remote file. I don't really want this "powerful" feature. Is it possible to disable this feature? I just want dragging files between remote and local panel to always be copy operation.
Thanks.

I'll consider this.
