[squeakland] problem with location of Etoys players

[Steve Thomas]

Lou,

The reason it is jumping to a new location is the rotation center of the
blob of sauce is not at the center of the Blob.
Also there should be no need to use smalltalk in your scripts you can
accomplish what you want with scripting tiles.
