As a developer of Sverchok that's not the impression I get when working with it and testing. We'd have a massive problem if we all experienced those crashes. It would be great to track down what's causing this, it would help everyone.\n\nFirst of all I don't get these crashes, and my setup is super lame. \n- win10\n- latest Blender\n- latest Sverchok.\n- no AN enabled. (ever)\n- no screen recording..\n- few background services.\n\nI expect that @nortikin , @ly29 don't get these crashes either and their setup is linux and osx, possibly with AN enabled (possibly not). But if we as _devs_ don't get these crashes, how do we even track down what's going on. I bet we do get (infrequent) crashes or hangs that we can somewhat justify during a heavy node operation (and don't want to wait for it to respond), but simply adding a node like `Objects In` should not crash Blender. Something's going on. \n\nI suspect any of these:\n- Either osx compilation of Python is wonky\n- some Draw function is incorrectly referencing or trying to modify variables.\n- AN's node tree _handlers_ are getting in the way  (tho i've not studied them.. ruling them out is worth the time)\n- Blender's Search (or our poll functions) in NodeView is doing something stupid.\n\nMostly I use `ctrl+space` to find a node, but ofcourse `shift+A` should be working too, but if that's where the problem is then that's why i'm not experiencing it. \n\n@enzyme69, if you get more crashes, please save the dumps as a gist and link the gist below (don't paste the dump into the issue here..)\n\nsome crashes from @enzyme69 's videos:  \n- https://youtu.be/4bKR9hChgmg?t=19m57s (adding Object In using Search in a new empty NodeTree)\n- https://youtu.be/rpMS6y8rFO0?t=1m18s (Adding Box node, using Search, not Empty NodeTree)\n- https://youtu.be/7TKRBFnAnLs?t=29m29s ( no idea...  that's good news )\n- https://youtu.be/sNLgdEDVPV8?t=21m39s (Adding Plane node, using Search)\n- https://youtu.be/Rl7tVsnzkng?t=13m53s (Connecting a noodle to skinviewer's radii socket)\n- https://youtu.be/vlw2S5kmk4Y?t=20m37s (Adding Line node from search)\n"},"comment":{"url":"https://api.github.com/repos/nortikin/sverchok/issues/comments/257233218","html_url":"https://github.com/nortikin/sverchok/issues/935#issuecomment-257233218","issue_url":"https://api.github.com/repos/nortikin/sverchok/issues/935","id":257233218,"user":{"login":"enzyme69","id":3952687,"avatar_url":"https://avatars.githubusercontent.com/u/3952687?v=3","gravatar_id":"","url":"https://api.github.com/users/enzyme69","html_url":"https://github.com/enzyme69","followers_url":"https://api.github.com/users/enzyme69/followers","following_url":"https://api.github.com/users/enzyme69/following{/other_user}","gists_url":"https://api.github.com/users/enzyme69/gists{/gist_id}","starred_url":"https://api.github.com/users/enzyme69/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/enzyme69/subscriptions","organizations_url":"https://api.github.com/users/enzyme69/orgs","repos_url":"https://api.github.com/users/enzyme69/repos","events_url":"https://api.github.com/users/enzyme69/events{/privacy}","received_events_url":"https://api.github.com/users/enzyme69/received_events","type":"User","site_admin":false},"created_at":"2016-10-31T07:58:23Z","updated_at":"2016-10-31T07:58:23Z","body":"Ok I reinstall and then run the \"Debug\" thing it hangs for under a second, but no crashing.\r\n\r\n![screen shot 2016-10-31 at 18 58 05](https://cloud.githubusercontent.com/assets/3952687/19847569/fc69d730-9f9b-11e6-907d-3d4ebf462966.png)\r\n"}}
