First the game works very good under IE 8 with current versions of Shock Wave Flash and Java from sun installed.

Under Mozilla tabbing several servers open can increase lag after a period of World chat spams and messages from system

Mozilla removes temp file data better than IE 8 but both force a relog for certificate acquisition after a cleansing of data

simply closing a tab and reopening a server with a login saved bookmark
provides a better refresh of data.

IE ver 7 also works very well

Safari has no issues not already found with other browsers

I would hope over time separate browser specific clients will become available
allowing for compatibility with production and review by PHONE
and play under different OS's and browser versions

there should be minimum version restrictions
like Windows XP home or Pro using only SP1 should not be allowed under compliance with Microsoft and the WGA program

it is also a good addition for multi account detection which I must add is very poor on Evony

Please do not use this statement to explore violating the EULA you agree to on account creation
i will be forwarding multi player detection methods to Evony staff very soon

Xeander has a good reputation with other F2P production teams on this issues so will Evony over time
