I'm not sure how to fix it, but at present I find the UP Resolution pop-ups requiring a vote on something or another to be annoying rather than fun.
Typically, there is nothing I want to propose. Perhaps a "No resolution" option? In its present state with the AI being no threat to me on anything, I find them gratuitous.
Also, voting should not be based just on one player/one vote. Voting strength should vary based on some other game metric (Galactic Influence? Trade?)
