Applescript used in an "Open new iTerm Window" Alfred action

Open New iTerm2 Window

on alfred_script(q)
  tell application "iTerm"
 	activate
 	
 	-- Create a new terminal window...
 	set myterm to (make new terminal)
 	
 	-- ... and go on within this one.
 	tell myterm		
 		-- Set the terminal size constraints.
 		set number of columns to 80
 		set number of rows to 42
 		
 		-- Array/List which will hold all our sessions (empty
 		-- by default OFC).
 		set sessionList to {}
 		
 		-- Create a few blank new sessions (will be replaced by
 		-- automatic calculations later, so that we'll have a
 		-- nice bar full with new tabs.)
 		repeat with i from 1 to 1 by 1
 			launch session "Default"
 		end repeat
 		
 		-- DEBUG: print the session list.
 		return sessionList
 		
 	end tell
 	
 	-- set the bounds of the first window to {w, x, y, z}
  end tell

end alfred_script

When I have already got a full screen iTerm2 and run this script in Alfred, I will get a new iTerm2 window and moves to the full screen iTerm2 workspace
