Thanks for the report! It looks like the Prerequisites section was removed - can you confirm if you can reproduce in safe mode?

thank you for your comment
It did not reproduce in safe mode.

Thanks for confirming 👍 If there's no problem in safe mode, then that likely means a community package is causing the issue:

http://flight-manual.atom.io/hacking-atom/sections/debugging/#using-safe-mode

You can disable each community package one by one to try and pinpoint which is causing the problem.

It may be that there is still a bug in Atom but if so, we'll need the maintainer of the package that is causing the problem to help track that down. You should file this issue on their repository so they can either fix the problem or tell us where the problem is coming from. The Atom FAQ has information on how to contact the maintainers of any Atom community package or theme.
