GearHeads Corner

When using the up-down arrows in the circular gear module to pick the number of teeth, if an arrow is left clicked and held, the numbers don't progress, but rather hit a certain point and start the cycle over in a narrow range.  If the arrow is single clicked instead, the numbers will progress in increments of one as expected with each click.

I removed the numerator (desired ratio) of the auto train ratio box and then hit the pre-set conversion ratio button and hit Search.  Program crashed because I did something dumb.
