9.10 to 10.04 Upgradeniggles

[Peter Hillier-Brook]

I recently upgraded 4 desktop machines and encountered a few minor 
irritations that I would like to resolve, hence this request for comment.

On a couple of the machines I was able to install the "Crux" desktop 
theme, but it is not available on the other two, nor can I find it via 
Google and it doesn't appear to be packaged for apt-get access. Can 
anyone help; I rather like the physical design and I can live with the 
lilac colour scheme.

On all machines there appears to be no linkage between Firefox and 
Thunderbird, so that selecting to "Browse All Add-ons" in TBird produces 
no discernible effect.

GRUB 2 is still a work in progress and has reverted to not saving the 
last used environment and always offers to boot the top entry in 
grub.cfg. This is obviously just a script issue and I will enjoy 
cracking it, but it's mentioned here for general interest.

One of my machines displays a dialogue box during logon saying that 
Power Manager is still running. A pointer to where this originates would 
be welcomed.

Thanks in advance.
