I'm getting tired of the stinking System Tool/Manual Tool glitch.

There are times that the program will crash and having changed nothing all the sudden a System Tool creeps into the program. Not one I put there... one that just shows up. Then sure as can be it crashes the toolpath during a cut.

I don't understand it. Nothing should change in a program unless I change it. Why does it change by itself. I see why a person on this forum had said that Bobcad is not time efficient (lots of wasted time chasing down things like this). I am tired of sorting through each CAM toolpath option to find the system tool that suddenly decided to creep into the program. Pretty frustrating and already hours of wasted time.
