I've only tested it with 2016 and 2017 I'm glad you got it working, i'm surprised it works with 2014. Thanks for checking it out and thanks for contributing
I think the "add selection to current layer" is available if you right click the layer. I've only used 2015 briefly before going back to 2014... Where the last version of outliner worked.
Like an XYShrinkWrap? I had a script for that which worked in 2012, but not for 2015 unfortunately. Give it a look around the web if you can find one that's up to date.
What kind of hardware? Updated video drivers? Why 2010? That was probably one of the buggiest releases there have been in max history. I would jump to 2012 or go back to 2009.
