Thanks again ElDiabloConCaca - Authenticate would be reasonable although I would prefer if I wasn't asked - it is my computer, I set myself as administrator and don't think I should have to authenticate. I've just had a similar occurance when I tried to install a new version of Ten Thumbs Typing Tutor by droping the new version into the Applications folder - so that it would overwrite the older version - this is a common way of upgrading in OS X - but I am informed that I cannot do it as I have insufficient priviledges... again, I'm going into the root... I have just had to do the same in order to upgrade OmniOutliner too.
I am also being asked to enter my password to simply put an Alias, a .dmg or application in the bin - an app I understand, maybe at the limit a .dmg too, but surely not an alias!
I have had a lot of weird issues with this machine and have been very disappointed with it...
Another odd thing that keeps happening is that certain websites and programs that I download insist on giving me either the French or Spanish versions.
I have the feeling that we got a rough machine - everyone tells me they've no problem with MacIntel, but since we bought it in 2005 we've had stacks of problems - nothing you could take the machine back and say 'It's broken' but crashes, the whole machine freezing up requiring a reset - all things that still don't happen to my Powerbook PPC 1.5 GHz which is still running the latest version of Leopard without a hitch...
