Sorry for the delay. I did some tests with 1.1.8, same problem.

The code looks like this:

ArrayList list = new ArrayList();

list.Add(new MyClass());

MyClass one = new MyClass();

bool result = list.Contains(one); --> return false with mono, true with 

I'll add this to bugzilla next week.

Thank you
