When I first installed it had war as a default. I was wanting to try the new battletech plugin, but it took a while to get it to download, but in both cases the tabs at the top were not visible. I'd see the game logo in top left right up against the title bar. To its right the play canvas. I tried maximizing, resizing, and resizing the left side as well. They never appeared. ( I once long ago used lackey on. A win 7 machine, and I remembered the tabs.).
