DIYLC keeps crashing on mac OSX 10.6.8

What steps will reproduce the problem?
1.Attempting any changes to my project
2.as soon as I try something as simple as moving one end of a wire for example 
the programme will crash
3.I have tried changing the sizeof the Java heap as suggested in some threads 
but this has made no difference

What is the expected output? What do you see instead?

different machines.  one is an iMac 2.16 intel Core 2 Duo.  The other a macbook 
Pro 2.4 Intel Core 2 Duo
