I apologize in advance for what must certainly be a basic question, but how in the world do you turn on the "bubble" to push and shove traces? I was battling a via that I couldn't delete (finally fixed that), but somewhere in the process I turned off push and shove and I'd like to get it back. I can see that bubble is off because 1) I'm stepping all over my other traces when I try to shove a trace and 2) while I'm in the process of moving the trace I can see that it's off in the options window...but I lose the ability to change the setting in the options window as soon as I stop moving the trace. I don't know how to navigate through the menus to actually turn it back on.
Any help is greatly appreciated with a simple but frustrating problem.
