I have had a long-time problem with
Mono and the Mono-based applications that, for reasons I do not understand, come installed by default with Ubuntu.
For those who don’t know about it, Mono:
provides the necessary software to develop and run .NET client and server applications on Linux, Solaris, Mac OS X, Windows, and Unix.
That sounds pretty innocuous on the face of it. But Mono has a potentially fatal sting-in-the-tail for some, and leaves a rather nasty taste in the mouths of many others…
