I have been testing D-RATS ver 0.3.1b1 with DVTOOL 2.0 beta2. Today I installed beta3 and when I tried to start D-RATS it just flashes a window on the screen and goes away. I went back to D-RATS 0.2.11 and it runs OK. I am running Windows Vista Home Premium and there were two updates installed today. I wonder if anyone else has had this problem. Bob, K8OMS
