I've determined what "instigates" this, but I find that it only mainly affects mintty and somewhat affects emacs. I've never seen a symptom in any other application. I use a tool called "Windows Caffeine" that is used to keep the display awake. It sends a "f15 key up" event every 59 seconds. That is what is producing the "~" character in the mintty window. I've also seen a symptom from this in Emacs, but it's harder to produce. It's not as simple as just having a text buffer in focus. I haven't been able to reliably produce it in Emacs, but the mintty symptom is very reproducible. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
