The Splash Screen appears for a second, then the application quits. I recall seeing a fix for this about a year ago which I think involved blocking adobe in the Hosts file, b ut thats all I recall... any suggestions? This is a corporation so I'm kinda locked in 4.6 and am not supposed to upgrade to the apache version.
