I don't know if this is really a bug or not, but a common way to use the run
dialog was to quickly run a certian program. So say I am typing in gedit, and
suddenly decide to bring up evolution, I just hit the run dialog shortcut and
type in the program.
Currently, because of the new metacity behavior, the run dialog comes foreward
unfocused. Not only that but it also popups up in the front of the tab list,
when the 'current' window (i.e. the gedit window) is second in the tab list.
Meaning that I have to tab through the whole tab list to get to it.

(Note: I am CC'ing the metacity maintainers since this bug might also be on
thier side)
