I have waited and played beta .31 now since release and have had only one problem that is repeatable on at least 2 different systems. The problem occurs if a auto popup screen like research finishing. For approx 4 turns the enter key on either position does not activate the turn buttonf. Size of game, contents of game, length of game do not seem to change this.
It has happened on both and XP pro and a Windows 2000 pro systems. Have not found any error traping for this, so I have no way of determining what or where the issue is. Both sysytems have different keyboards, on using the 5.2 microsoft multimedia keyboard software, the other using the generic microsoft keyboard driver.
If I am able to find out what or why I will post.
