Bug 14228 Too easy to create duplicate methods
Build 20020418 - I was browsing some source (not even actively editing). - Suddenly I noticed there was a squiggle on one of the constructors. - Hover told me that there were two methods (sp) with the same name. - Scrolled down to see that, in fact, I did have another copy of the constructor. Strange. How did this ever compile? - It turns out I must have inadvertently dragged the constructor a little bit in the Outline. - With the new DnD support in the Outline, it is far too easy to create duplicates.
