Thought I'd have a quick look at this messenger software - however at the end of the install up pops the standard 'Allow/Deny Internet Access' box from LooknStop - but this seems to then hang (title bar of the dialog changes to '...Not Reponding' and Trillian itself then also becomes locked waiting to access the net. I was unable to close either LooknStop or Trillian successfully with TaskManager - each time I tried the error listed was 'HungApp' but it didn't actually remove it. My only solution was a hard re-boot. After which I tried again but got exactly the same results. Removed Trillian - I'll stick to Windows Messenger after all !
