Sometimes when I open the "Characters" window to get access to special characters (e.g., greek letters), it re-opens itself repeatedly. The re-opening triggers on some actions, but I haven't found any pattern to those actions - sometimes it's typing, sometimes clicking, sometimes changing tabs in a browser.
Has anyone else experienced this? Any suggestions for how to kill that window and make it stay dead? Since it's an always-front window, the only think I can do is keep closing it over and over again until the problem goes away eventually.
