I have been experiencing this for a few days and it is becoming increasingly common. Whenever I attempt to use Atom, within a few minutes it locks up entirely and never responds. Any interaction whatsoever locks it up. I have shut off Avast (virus scanner) and it makes no difference (referring to the March 25th thread on reinstallation.
Really like Atom. Really hate not being able to use it.
Ok - I was opening a very large JS file (1.61MB) and it locked the application. What is the file limit size in Atom?
