Ok, this is interesting. I opened nwtest.capx from Giganten and tried it out on Windows 8.1 64-bit on an i5 2500K with Radeon HD 6850 (C2 178).
When I preview as node-webkit from inside C2, everything works great, but when I make a real node-webkit export, the win32 program freezes occasionally for 1-2 seconds. It goes down to 0 CPU during the freeze and I cannot exit the program until after the freeze. Usually it freezes once or more just a few seconds after I start the program, but sometimes it runs fine for minutes. I haven't managed to get any freezes in the preview node-webkit so far.
Ashley What difference is there between running a preview node-webkit and making a full node-webkit export?
Maybe it's related to some js minification that occurs in full export but not preview?
