unintentional breakpoints

How did you remove the breakpoint?

If your application / code has a lot of breakpoints - there is a global option to turn off all breakpoints. At the top where you see the Run, stop and Scheme options on the left - there is button to the right of these options called Breakpoints.

When it's selected, any breakpoint set will work. When deselected - no breakpoints will stop the execution of your application.

To remove certian breakpoints, just click them and drag them off the "gutter" when you let go a puff of smoke appears and it gone!
