I'm sure somebody has mentioned this before, but a quick search for 'slider' doesn't bring up anything.

I recently got the economic boom, and decided to adjust my focus to as much research as I could afford.  Turns out, I could put 90% there and was forced to keep 10% in social production.  When the boom ended, I was way in the red and had to readjust.  I didn't need any ships, so I left military spending locked at 0%.  I started clicking to increase social spending, and noticed that the research slider stayed all the way over to the right.  Not only that, but it took two clicks to make each 1% adjustment.  I got my social spending high enough to return me to a profitable economy (maybe about 30%), and the research slider was still all the way over to the right.  Out of curiosity, I clicked once on the decrease side of the research slider, and it jumped a bit to the left, but actually brought me back into the red.  It was as if it had reset the social spending to about 25%, even though the percentage displayed did not change.  Even now, with military at 10%, and social at 33%, the slider is still well to the right of where it should be.
