I spent hours trying to figure out why an op-amp wouldn't give me the 
output I was expecting. It finally clicked when I read the warning on 
the data sheet that pulling an input within 0.5v of V- would cause it to 
latch-up and force the output to near V+ no matter the state of the 
inputs. I went through a few chips thinking they were defective.... or 
that I toasted one (got V+ and V- reversed, which is apparently bad for 
op-amps...)
