[ale] [OT] Making Emacs transparent in Cywgin

[Jonathan Meek]

I understand that but also keep in mind that this trick will actually work
for linux as well. This is why I flagged my message as OT since I knew it
wasn't directly Linux but thought it might help someone else down the road.
Some of us are stuck working in Windoze world and it is helpful to try to
bring some of the comforts of Linux into our workplace as much as possible.
