It works fine on my other 2 machines… Just the one that matters most (the Pipo on my FABkit) is being ‘unpleasant’…
No joy with Canary either!..
Anything I can do for debugging on the Pipo side?
BTW: I’ve started DevTools, and the only thing I see, whenever I try to open an SVG is this message:
GET http://127.0.0.1:8080/sockjs-node/info?t=1493060125399 net::ERR_CONNECTION_REFUSED
in abstract-xhr.js:132
PS: Same error opening a workspace…
PPS: I’m a dev myself… Just not in JS, but most concepts I will grasp, because I speak C,C++,C#,Pascal,Basic,SQL,PHP,Perl, etc.
So if there is anything I can do to help debug this weirdness, I should be able to understand what I need to do! 
Nothing I can do to help figure out what is broken?..
I can’t think of anything. It doesn’t seem to be acting like Chrome on Windows normally acts. If I remember right, Pipo runs Windows 10, which is what I develop on.
Maybe it’s worth looking for unusual things. Does the Pipo come loaded down with crapware? Do you have any Chrome extensions installed?
Yes, it’s Windows10.
The old version works, but has challenges doing gcode generation, and doesn’t have all the fixes and improvements of the last month or so…
The new version runs, but doesn’t open any files… (so not just SVG, also workspaces, settings, gcode, nothing!)
And every time you try to open something, it logs the above message… It’s strange it says Connection REFUSED
I can give you remote access over TeamViewer if that helps?
LOL… That’s cool! 
I just updated Chrome to the latest, but that made no difference either!
It accidentally opened another SVG once, just now, but can’t open it again!!!..
Completely uninstalled LW4 and Chrome, rebooted, reinstalled it all… No difference… Still not opening known good SVGs! (nor Gcode, workspaces, snapshots, etc. It’s as if any file open operation is not executed!)
I manually removed the lw.comm-server folder, so that should’ve wiped localStorage, but I tried it anyway, and then restarted LW4… Still no difference! 
@Todd_Fleming no crapware, no extensions. This Pipo is screwed to the FABkit, and dedicated for that purpose! Only additional tools on it are InkScape and TeamViewer…
Ok… Not sure what I did, but I was doing some testing for Live Jogging, and when I was done with that, I wanted to do some more testing on the file opening… And it just worked!
I haven’t tested the other filetypes (gcode, workspaces), but opening PNGs and SVGs at least works!
(I did find a possible bug in the gcode generator, but that’s something I need to further investigate!)
I guess it’s the Electron window then…
And now it’s not working anymore… Aaaaaarrrrgggghhhhh!
@CescoAiel I just added some extra logging to the live version to try to narrow this down. Try loading an SVG file and post the console log. I’m looking for the entries which start with “loadDocument:” and “FileField:”.
