Julian,

A while ago I tried installing a parallel copy of Mono in order to get
an upgraded mono installation. I have read that on Ubunto systems you
should not tamper with the mono installation. Anyway I needed an
updated version of Mono to run a .NET program for work. I ended up
running into too many problems with that process so I bought a winxp
seat and installed it in virtualbox. Expensive and frustrating as Mono
should have been capable of running it, but the workaround that was
recommended was taking up far too much time. Is there any possibility
of decoupling mono from Ubuntu a little bit so that it can be kept up to
date? What happens if security vulnerabilities are found in the version
of Mono that Ubuntu is apparently built upon?

Anyway, I do not recall which files I needed to modify, and would have
to search for the instructions on installing parallel versions of Mono
to refresh my memory as to what I did and where I stopped. I don't
think I got very far.

By the way thank you, that appears to have solved a very frustrating
problem.

John
