I am facing this peculiar problem. Whwn I click modifier list, max stops responding and it simply hangs. If I try to open modifiers through modifier menu, it works but hangs again if I try to select subdivision surface modifier. Can anybody help me. I am using max 2009 and 2011 and facing the same problem in both. I downloaded the latest service pack as well as hotfix and installed but the problem is still there. Please help.
