Quick CATIA Tips: Avoid zoom on the specification tree

One annoying aspect of using CATIA is when you attempt
to click one of the little plus signs in your specification tree but you
miss and accidentally click a branch instead. Your models goes a shade
darker and when you try and zoom in on your model it instead makes the
tree get enormous or extremely tiny. To turn this option off simply go
to Tools>Options>General>Display>Tree Manipulation.
