I know you can change the position of a window using smt like
var winGeom:WindowGeometry = new WindowGeometry();
winGeom.topleftx = 50;
winGeom.toplefty = 50;
but that goes for the 'main' extension window. Or can I use this somehow for new windows - like my tooltip - as well?
_preview.nativeWindow.x = 400;
seems to do the trick.
If I'm not mistaken, tooltip window types are going away...
