I was making a Downloadable build file for a friend and when I went to create a readme file my entire screen froze and flashed blue. This happened as well when I went to sort my downloads.

Any idea what this is and how can I fix it?

I'll be honest, that was very difficult to understand because almost all of OP was a run-on sentence.
