Hi,

Well I am trying to do something a little interesting.  I want to
display a graphic with a demonstration of my latest GP tree built.  The
demonstration is to visualize how the GP is learning through iterations,
but I am having some trouble creating my dialog in the postEvaluation
section of the statistics... Below is the stack trace that I receive...

AWT blocker activation interrupted:

the GPGuiRunner is simply a wrapper thread class.  I thought that it
would be less affected if running within its own thread, but it seems
that the thread that is responsible for the statistics output cannot be
blocked (always immediately results in a InterruptException)... I have
tried to find out why this is so, but so far to little avail... I need
to know how to do this ASAP unfortunately, as the assignment is due
early next week... Thanks... And by the way great tool you have developed!!!
