Out of curiosity I searched the registry to see what items were stored by xLights. (Turns out just over a dozen or so). One item that came up during the search was the system PATH. It turns out, that every time I installed xLights, it kept appending c:\program files\xlights to the path, even when it was already there. While it doesn't pose any issues that I know of, just thought i'd bring it up, as it shouldn't keep adding it if it's already there. I cleaned it up on my own by removing the unwanted ones... turns out I had nearly 20+ xlights entries in my PATH. Here are the before and after PATH's.
