I can confirm that going back to 0.86 version of nw fixes the problem....
i have tried with 0.8.6 and the freeze bug is still here :/, i have tried all previous and post 0.8.6 versions of NW too.
there are other methods to compile html5 code to exe? or any alternative solution for this problem.
i have buyed construct and im working on new project but this problem stop me from go ahead and i dont know if here will is any working fix soon.
