Yes, anyone running just the base game in TS2 needs the patch but once you install any of the expansions that rather becomes null and void as the expansion updates the game and sorts everything out anyway

But back to TS3 and your pending computer arrival

I hope it arrives soon, Christmas has arrived early, yay, great news

I will have someone to exchange notes with as I think only you and I will have '7' here (or if anyone else has it they are keeping very quiet about it, lol). If you are coming up from XP them 7 will feel very new and shiny (although anyone using Vista will be instantly familiar) and XP will soon feel very dated by comparison.
I tend to run fairly recent versions of everything and I am not experiencing any problems at all other than the fact that the Canon RAW codec won't generate thumbnails in explorer for .CR2 images even though the image will render correctly once clicked

Canon, in their wisdom, decided NOT to support 64 bit for the codec in
Vista and that has a knock on effect in 7. They need to wake up and smell the roses however as 64 bit is the here and now

Whilst waiting for them to get their finger out I am currently using Picasa which is optimised for all RAW files as they emerge. It's a niggle for me for sure given that almost everything I do revolves around RAW image files but its not insurmountable.
Looking forward to your opinions on the new OS. Don't forget that 'search' is very good now. If you can't find something you want on your computer don't waste loads of time looking for it just put its name into the search box and it will pop up on your screen. That goes for programmes, cmd line utilities, emails, your music.....pretty much anything really.
