Furthermore it's not just that it didn't look identical to the rest of the OS. There is in fact no culture for Windows apps to conform to the platform specific look and feel. A long time ago people were discussing inconsistent ClearType use in Microsoft's own apps like Office and Internet Explorer: it turned out that both Office and IE had their own settings for enabling or ignoring ClearType. In my opinion, that choice should belong to the OS and should never be given to app developers.
Yeah as a person who only uses Microsoft Windows when absolutely necessary, who consequently has not been conditioned to overlook its many quirks, I find it hilarious that someone would judge an app for not being consistent with the look and feel. To see how unrealistic this complaint is, all you have to do is launch the Control Panel, then launch the Device Manager, and compare them.
Not sure why, this is like fallacies 101. Just because many other surrounding applications are inconsistent in their presentation, that doesn't mean this situation should be worsened.
