dhous616 - I am blown away by the problems you describe in your post - I have 4.0.3540 with NO issues as you described. Performance is exceptional. I have not had it hang even ONCE and let me tell you I am on it CONSTANTLY for my job (oracle / sqlserver dba consultant) I think you should open a 'ticket' with support as I am sure there must be something 'machine specific' or perhaps you did not get the latest patch! I assure you the support folks are very good at helping figure out an issue a specific user may be having. Good luck!
