My GF is running the game on Windows 7. I got her set up with the Playonline version for Windows 7 and got her set up with Windower, the plugins, etc. She loads the 'Launcher' (Mandy icon) in the Windower folder but the playonline bar at the top where it shows the version does not have 'Windower enabled' like it shows on mine. After clicking 'Play' it just loads the game Fullscreen as if Windower isn't there.
