Hi I have been using 2.1 for a while and just was playing with 3.2. I just noticed a possible bug. This happens with the default skin have not tried with others yet.

When you click the buttons that are suppose to reduce or increase the gap, in the old version you could click one at a time slow or as fast as you want to change the gap at the speed you wish to click. In version 3.2 if you click that button too fast it acts as a rotate button. If you are simply wanting to close or open a gap fast with clicking you can not do it with this version.

What you're seeing is the doubleclick, which rotates the calieprs to zero or ninety degrees. It's a new feature in 3.2.
