So are you saying that you see this problem on the current version of Windows that you're running, but whether or not you see the problem depends on if the file was created before or after you updated Windows? How are you creating these files?

Does the file you attached show the problem or not? And could you explain exactly what you're seeing, versus what you're expecting to see? It's not clear from your last message. For example, what is the value of the variable "settings", and what do you expect it to be?

If you have two files on your system which currently show the problem, please attach them both, with different names, and tell us which one shows the problem and which one doesn't.

My only guess is that this is related to encodings or line endings.
