No you dont. But the graph editor works just as long as you reset the copy settinbgs thsi swithces you bvack to the 6.0 6.5 behaivour. To do this choose copy[optionbox}->edit-> reset settings (wich is way noicer than trying to delete prefs). I suggest you do thei even if you dont want to use grap editor because soomer or later this gui designers MAJOR blooper is going to make your life horrible.
Thing is the GUI for options is broken and thius whatever you select from the window just screws up anything you might ever whant to do!
Worst is you dont see any difference when resetting settings but the difference to what happens is HUGE!
