Okay. Here's the deal...
Moments ago, I tried sending a file to FreeCommander.exe (see freecommander.com ), a freeware file manager for which I have great affinity.
The path includes spaces (ah la "Program Files"). On receipt of the command, FreeCommander returns "FirstWord" not a valid path.
I don't recall this happening elsewhere, never mind I don't recall what I did five minutes ago, but I digress.
As much as I love FreeCommander, I realize software is subject to erroneous behaviour, here and there. Thus, I am not confident in /pointing the finger/ in any direction, in this case. Not to mention, pointing the finger is rude, nevertheless, by the way.

I checked, and I am using v2.1
