Gnome 3

Pylight commited the issue that a QDialog, i.e. the answer dialog, can't be moved.

This link will solve the problem: http://ruionwriting.net/2011/06/cannot-move-dialog-windows-on-gnome-3/

"There are those who hate, other who love and others that really don’t care why dialog windows have strange borders and don’t allow you to move them grabbing the title bar, oh wait :P , where is the title bar?

The solution is simple: gconf-editor to the rescue. Just open gconf-editor and untick /desktop/gnome/shell/windows/attach_modal_dialogs. Press Alt + F2, type r and press Enter (reloads gnome shell). Now you have the normal behavior back."
