Hi, I have a wierd problem when I play a game in Vista on my iMac using a wireless Mightymouse. Vista finds the mouse and everything, but im having difficulties with right-clicking in games. Sometimes it works fine, others it does not - in the same session. For example I play Age of Empires III or World in Conflict. When I want to move some people from A to B, I select them and right-click on the spot where they are supposed to move to. Then they do. Then I take some other people and do the same, but nothing happens. Instead the people become un-selected. When you try to select a piece of "ground" in Age of Empires, clearly nothing happens, since there is nothing to select - and the way I see this, sometimes the game can't really understand that I am trying to move theese people (right-click), not select something (left-click). Do you understand what I mean? It is very annoying, since I cannot really play the games with this issue. Will it help to connect a USB mouse for example?
