I came up with a slightly cleaner design for this an hour or two after I originally saw this topic but I haven't had any time to implement it - maybe if someone else has some free time to play with it they can bring it too life?
I like the new messages count, I'll do that. But the rest is a bit too...line-less for me.
I planned on releasing a new version soon, which works on .NET 4.5 only (no XP). Is .NET 4.5 already on Windows Update ?
My current installer doesn't have a bootstrapper to install .NET, so I can't use the automatic update method to give a version that won't work on most computers.
@Neobond: The leaks should be fixed in the next version. There still is one small leak, but I can't control that - if you quit all the channels, there's a high probability that some users will stay in memory. But that memory will be freed next time you open a channel, so it's no big deal.
