There are moments in every Mac users life that are common across our experience. We all have that moment of abject horror when we install an upgrade to an application and the result has us screaming like we just saw a new set of scars on our face. “Oh God,” we shout, “What have you done to my beautiful application?!”

Today’s unfortunate victim of a poorly-thought-out interface “upgrade” was FirstClass, which upgraded to 8.1 today. FirstClass is a great piece of groupware, but the development of the Mac client has always lagged behind its PC counterpart. Today, it received some much needed upgrades including anti-aliased text, better voicemail handling and a few improvements to the admin interface. But, in the midst of those changes came some unwelcome additions and slowdowns in the application, and now I’m faced with a client that doesn’t even work at all.

Sure, it’s easy to back up to an earlier version, but there’s nothing more disappointing than a failed update.
