This is what I get from x86 and x64 builds both before and after killing the nw.exe processes in task manager:
[0210/030956:INFO:nw_package.cc(175)] "D:\Users\Erik\Desktop\Prototype\win32\nw.exe"
[0210/031229:INFO:nw_package.cc(175)] "D:\Users\Erik\Desktop\Prototype\win64\nw.exe"
Maybe that's an error code of some kind? Doesn't look like it though.
Rambletime: The special coddling that NWjs requires to get going man... Lag spikes that come and go, demands fresh gfx drivers at all times, doesn't like integrated gfx chips, doesn't like Optimus, doesn't like Macs or Linux OS'es, doesn't like recording software, etc etc...
