Differences with vim 7

[Robert Cussons]

I just installed vim 7 on my linux system at work (more specifically 
debian sarge running KDE 3.3) and I get a few funny things happening. It 
is installed in my home/bin directory as I don't have root permissions. 
All comments seem to come out underlined and the fonts for everything 
including the menus are different to before, I don't know how to check 
the current font setting, but when I type :set, there doesn't seem to be 
anything that would have changed the font listed. Anyone had the same 
problems?

Many thanks for any help,
Rob.
