I have 2 accounts.  I've just got a character on my second account to a similar CL to one on my first account so wanted to play them together.  I have 2 screens.  I wanted to have 2 clients running side by side so that I could see what was going on rather than having to alt-tab between the 2 windows.  I play in windowed mode (in 1920x1080 but have tried it in 1600x1024) and when I move one window to my second screen the mouse stops functioning.  I can still use keyboard commands, but clearly it would be nice to be able to select things (loot for example).  I've selected all the options on the launcher but nothing seems to help.  Am I missing something obvious?  Am running Win10 if that helps with any diagnosis.  I don't think its a PC issue as I have quite enough grunt to probably run a fair few clients if I keep them all on the same screen. I can kind of cope with the clients needing to be rebooted when I alt-tab to the desktop for any period, its annoying but understandable, but not being able to use a mouse on a second client, on a second screen is a little limiting.  Any ideas?

Hi, am returning too.  When I go to fileplanet, the page you link to no longer works and there is no option for an EnB key anywhere.  Help please.   Edit:  nm, sorted.  Note to others, read the forum post on how to get into the game :)
