Just spun up Jenkins on Windows; I'm coming from Hudson on Linux, so maybe I am making an amateur mistake...

I have installed my favorite Extended Choice Parameter and configured it as I was used to, but no good. This is what I did...

Created a file on the Master node called C:\support\traders.txt. In the file, I put:
BOXES=a,b,c

Then in Jenkins, I put the absolute path to the file, C:\support\traders.txt, in the Properties File field, and BOXES in the Property Key field. It finds the file, but not the key value pair inside. Error is:
C:\support\traders.txt exists, but the provided key "BOXES" doesnt exist in this property file.

Setting this up is usually pretty straight forward, so now I am wondering if there is a bug in the new version, perhaps with my version of Windows or something...

Any thoughts?
