Colin Findlay (PCW September 2008, Letters) appears to have only purchased the trial version of the game.

In the full version, the successful conclusion of the Vista level allows players to proceed to the advanced level: Office 2007.  

This brings with it a whole range of exciting new sub-plots, including "Find the menu command" (which can keep players amused for hour on end) and "Spot the bug". The latter is especially exciting because the inventors have carefully spread a mixture of bugs around that repeat consistently.

I found a nice one in Excel called "print selection", which only prints the first six lines of the last page selected. Then there are those that appear almost entirely at random - the one I found lets Word refuse to show text boxes in .doc files written in Office 2003, but it only affects some text boxes, so you never know if they should have been there or not.

Sadly, the game has no check-list of clues, and even if you contact the supplier they will keep you guessing!

Office 2007 is not for the faint-hearted gamer. After three months I admitted defeat and decided to restrict my play to the Vista level. Even then, Office 2007 wasn't finished with me, as it decided to port one final game over to Office 2003 - the famous "make the EULA pop up every time I start the programme" game, which can only be completed by editing the registry.

If only these guys at Microsoft could develop real programmes that were as clever as their games!
