Well, i think this is a stupid thing to ask for, but i think there is no problem writing down cause this forum area is made for this... And maybe there are other users complayning about it too On Mac-OS X, when you click the red button in the major 90% apps, they just close the window and go to dock, and stay quietly right there with all the stuff open. Check iTunes for example, it keeps playing. Here in parallels, when you hit the red buton... no, there is no explosion caused. The program simply shuts itself. And 99,99% the times I use the red button (or even the "mac+w" command to close parallels window) is because I just want to wrap it off the desktop. As I use just one instance of Parallels at a time, the "File -> Hide Parallels" (Mac+H)" command serves me great. But I constantly use the mac+w accidentaly, so i think you should atribute the red closing button just to hide the window in the dock, and the same to the Mac+W key. PS.: I speak portuguease so sorry if I hasn't been clear enought
