Hi
Its hard for me to tell without viewing
your code.
Somthing is not initialized and still has
a "null" value.
This can happen when you declare a variable
at the top of your file and then later in the code
initialize it in a method, but if that method isnt
called before the mouse event takes place, you
will receive a null pointer exception.
You can email the code to me or post it here
if you like, then its easier to help.
Good luck Phill
