Subject: handle more focus events. keep track when focus goes to another screen and don't... 
X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=7c17296a20f3ff6e2a2f8c049ff96c0ab1fac624;p=chaz%2Fopenbox

handle more focus events. keep track when focus goes to another screen and don't handle focus fallbacks in that case until we know focus came back to our screen.
