[Pharo-project] Morph wont delete in pharo, cant select it...

am i doing something obviously wrong?: i have downloaded Pharo 1.1.1 (single click) for Mac OSX bring up the image then: Morph new openInWorld, do it. (get a nice blue square, perfect) click to pick it up and move it around, all is well control click, brings up menu for morph here is where the problems start delete menu option, Blue square wont go away... add halos menu option gives halos but they are on the PasteupMorph (the desktop i think). i cant find any way to get rid of this morph, will i have a blue friend forever? im sure im doing something obviously wrong, just dont know what it is...
