I think the find button is just broken atm, I can't get it to do anything useful and there seems to be al sorts of weirdness going on.

Maybe thats a special type cos the same thing hapened to me and it worked fine....beta 3 even though its doing funess now its Very unstable....when the latest version of beta 2 was out i bet it was quite stable. you add new features Extreme ones hell can break loose So you work on them for months or so and their well done and do not malfuction so all the core features of the game are operating well only a tad bit of em don't function like the details part of a planet... i wanted to start a propaganda machine because i couldn't bulid soil enchancement social projects.. still didn't work... lucky me that my civs didn't know how to rebel at the time STILL a few things were out... but its good progress
so keep working until yer heads explode....

I have a different bug which has persisted in the Beta 3 release and patch: After colonizing a planet I get 3 choices one evil, which gives biggest bonus ,in this case starship bonus, one good, and one neutral. There is no method to choose between them. The mouse pointer does not do the job. So I am stuck there and have to alt esc and then close the game.

You need to put this in a seperate thread, mixing different topics in the same thread makes it difficult for stadock to find and refer to.
