Greetings all,

I've been playing this game for about 2 weeks now and something strange has just happened.  When I played before today and wanted to build a lab or a rail gun, I could select where to place it and then click to build there. 

Now when I click to build a railgun, it sticks it right next to my frigate factory and does not allow me any choice.  Same with Labs, i click to build one and it just lumps it in with the frigate factory.

Is there some way to fix this or have I hit a key on accident that locks where builds happen?  I'd really love to know because at this point i really dont wish to play if I cant select where my units are going to be built.
