When playing Age of Empires 3 on Windows 7, how to get the screen to appear in the center

The British Black Watch Kick.

Takes advantage of the British strengths to get the economy up and running very fast.

Direct from the guide, the different strengths it plays to:

• The 2 falconet card, an excellent card indeed.
• The opportunity to create 8 Black Watch highlanders from the church VERY quickly. Highlanders are great anti-cav units and all-around bruisers.
• The Black Watch are delivered in seconds, unlike conventional mercenary shipments, which take 1 full minute.
• The Thin Red Line is also available from the church.
• Excellent economic recovery due to the manor boom.

I can see you've tagged this AOE 2 - we play LAN games of AOE 2 in our office network successfully with a mixed environment of Windows 7/XP machines. We did notice some issues with the colours in AOE on Windows 7 that were related to a clash with the windows theme - you can see the solution for that at: http://social.answers.microsoft.com/Forums/en-US/vistagaming/thread/a1763d12-11e2-498f-9b23-122792b14f74

With the networking, the only issue we saw was that the Windows Firewall blocked outgoing/incoming connections by default and we had to add exclusion rules for it, by clicking 'Unblock' in the dialog that pops up when the game runs. You would need to 'Alt-tab' out of the game to hit 'Unblock'.

Edit: Also, I have seen success disabling extra networks (wireless, lan, hamachi) when you're trying to play. Sometimes, for whatever reason, an unused/enabled lan network keeps you from connecting with your wireless one. Hamachi is great if you're using it but should be disabled when you're not.
