UO Second Age

I downloaded the client from the ftp server installed it, patched it , installed razor and net framework too. Now when i open the game from razor the client starts in full screen. How can I fix this?(because i cannot alt + tab)

When you're in-game and have a character, open up your paperdoll and click Options, then go to the Display properties. Once there, you un-check the "Use full screen display" button. You might need to restart UO for the effects to take place.
