Problem
In windows failover cluster manager, clicking on an node in the tree will raise the following error:
This is one of the biggest error messages I have ever seen in a Microsoft product, that is, regarding the size of the message box . The error states: “A weak event was created and I lives on the wrong object, there is a very high chance this will fail, pleas review your code to prevent the issue” and goes on with a .net call stack.
