On a few occassions I found that nwjs has filled my entire 32GB Ram causing the PC to grind to a halt at a time that I was not actually running Pinegrow. If it happens again I’ll try and find out more but it’s hard when the PC has no ram left! I notice after I have closed Pinegrow normally that in Task Manager one instance of NWJS process is still running using 16% CPU and 256MB Ram. When Pinegrow IS running it may be that there are 8 or more instances of NWJS. Why is one left after close and what is it doing? (Pinegrow 6.12 Windows 10.) Task manager after Pinegrow used then closed: ![nwjs](https://canada1.discourse-cdn.com/flex036/uploads/pinegrow/original/2X/7/7a3d526c3be35953c27b68a8c08503434b093878.jpeg) Task manager Pinegrow in use normally: ![nwjs 2](https://canada1.discourse-cdn.com/flex036/uploads/pinegrow/original/2X/b/b2db64f4b16af99a27166e9667cbb20457cbb87d.jpeg) ---

> Sometimes a process called `nwjs helper (Renderer)` is left after Pinegrow quits and it consumes CPU and memory. This appears to be a NWJS issue and we can not fix it directly. In this update we added a code that explicitly terminates the process on Pinegrow exit. Please let us know if this has any positive impact.
