Blooglspash: Just click on the object, hold down the left mouse button, drag to where you want it on the wall, and release the button.
DadouXIII: Oh OK I see.
My problem is that I could not see where the wall actually was.
To anyone wondering: The wall is where the height graduations are marked.
Thank you for the reply, all this garbage was cluttering my desk the whole time !!!
I was even getting crap from the inspector for this :)
If you have anything other than the official plaques hanging on your wall, then you'll get fined for it when the inspector comes around. Make sure to take anything unofficial (your son's drawing, the banner etc.) off the wall before he arrives in your office.
