A couple of things I've noticed on the Windows version.
Not a bug really, but a minimize button would be nice. Sorry, I mentioned that elsewhere, but thought I would put it here as well.
Secondly, I use dual monitors and have them extended so I can have multiple window open.
Practicing PCEA on one monitor has no effect the second monitor. But, when I start to play a game with another person, the WGT game disappears and will not open back up until I close all open windows.
Thanks
