I have recently had 3 instances of SoapUI hanging when I run a TestSuite. Just before each hang I had used drag-drop to rearrange the order of TestCases within a TestSuite. These shouldn't be related but I can't find any additional commonality between the hangs. I'm sorry that I don't have more information, I can only say that this wasn't the first time I had run the case in that session.
