Congratulations Microsoft. Seriously, you finally managed it. After years of using your MSN Messenger and Live Messenger clients in favour of any other (on Windows at least), you've shown me the error of my ways. I could have converted to Trillian or Pidgin and prevented myself from being stuck with ads in an interface which defies even your own GUI standards and best practices documents (not to mention interfacing with the rest of the system in a cock-handed way). Instead I stuck with it. It's the official client, that must mean something surely? Apparently not. I avoided this latest upgrade because I didn't much like the changes that had been made (every big release seems to expand the interface, soon you'll need an array of nine panels just to show the menu bar).
Eventually though you pushed the big red button and I wasn't allowed to log in unless I upgraded. Not because you wanted to force me over of course. No, this was for my protection. So sweet that you think about me. So I dutifully clicked the upgrade button and braced myself for what was to appear.... It didn't. Any attempt to log in now crashes the thing. Apparently I'm not the only one, and (being an average end-user for once) I really can't be bothered trying to apply the fixes on the off-chance they might give me another half a year before it breaks again. So now I'm using Pidgin as my sole client across Ubuntu and Windows. Something I should have done long ago.
