Beyond the just weird oddities I get in Lion, this one takes the cake. My browser window is now on the dashboard screen! I have dashboard set up as a space (lion default setting) and while FCP was launching, I was messing around in the dashboard with widgets. FCP kept trying to dump out of dashboard while it was booting, and I kept swiping dashboard back on screen. Along the way, the browser window stuck.
I wonder where it'll go if I switch dashboard back to the Snow Leopard style? We'll see.
