Hi!
It's possible to go round so you don't get the penalty from trading
technology with another player.

All you need to do is switch your current research to another before the
trade and after the trade switch back to the one you were researching
before. And the bulbs return to the amount they where at the beginning of
the round.

This works when you have been researching the the technology you currently
research for at least one turn. And you must be able to switch back to the
same technology after the trade.

This is so because it keeps in some buffer the status of research that was
at the beginning of the turn so if you change your researh by accident (fe.
the help checkbox wasn't on) you wont loose lamps when changeing back.

FIX: When a trade that contains techs is accepted clear the register,
buffer or whatever it is.
