Hi Doug,

I wouldn't call it a compiler bug : the ampersand
(concatenation operator) is stronger thn the 'is
within' function, so the engine interprets your
version as :

  addToStatus ("within: " & the mouseLoc) is within
the rect of the target into withinCheck

which of course creates a problem because now it
doesn't have a point to check with the 'is within'
operator.
To avoid this, simply recode to :

  addToStatus "within: " & (the mouseLoc is within
the rect of the target into withinCheck)

Hope this carified things a bit,

Jan Schenkel.
