Hello All - I have a reproducable bug on version 1.21.017 (Pro) using two laptops playing Vanguard. I can launch and play both games normally, but after 2-3 minutes I am unable to rotate the screen using either my left or right mouse button once I have moved over to the second system to cast a spell and moved back to the primary system. Does that make sense. I can play the game normally so long as I dont access the second system and use the keyboard while there.

I only see 3.20 as well. I've tried switching servers and updating my xml.... no dice.
