Re: NWC files not opening properly

Have there been recent changes to your system, like a Windows update?
I haven't seen the behaviour you're describing in NWC, but I have certainly seen it in other software. This makes me think there's most likely a Windows glitch of some kind.
A google search using this search term "Double click file and application opens but doesn't open file" returned a bunch of results - many, as usual, didn't appear to be particularly helpful, but that's my best suggestion for now.
