Node-webkit Helper causing system hangs

Question

I'm using the intel XDK developer tool and having frequent system hangs when node-webkit Helper is accessed. The CPU use in monitor is ofter in excess of 100%. I've seen other people having problems with node-webkit Helper on OSX with different apps. Does anyone know of a solution for this?

There are two fairly common reasons why an update doesn't work properly:
1. Use of a Delta updater instead of the Combo Updater. The latter seems to cause fewer problems or, rather, may "fix" some problems that the Delta updater misses.
2. The user needed to repair the hard drive and permissions prior to installing the update. This is the most common problem. Installing an update on a system that is corrupted or where permissions are invalid will usually cause the resulting updated system to malfunction.
In some cases there are actual system files that have become corrupted and cause an update to malfunction. If this be the case usually it's necessary to do an Archive and Install to replace the old system (hard drive should be repaired prior to doing the Archive and Install.)
Among troubleshooting efforts to try are: (1) boot into safe mode to see if the problem is solved. Safe mode disables third-party startupitems, contextualmenuitems, and extensions; (2) create a new user account and log into the new account; A new user account has no login items or old preference files. If these are corrupted the system will work properly in the new account; (3) Use a utility such as TinkerTool System to clear user cache files, font files, and log files. If these become corrupted they will cause the system to malfunction.
Install the freeware utility AppleJack (www.versiontracker.com) on each of your Macs. In the event of severe problems you can boot the computer into single-user mode and run AppleJack to fix many items that cause problems. AppleJack is only run from the commandline in single-user mode.
