hi nice pharo people I'm doing my very initial attempts in Pharo. Having read something here and there. Now I've put myself to subclass BlElement in order to add a method of myself to this subclass. The subclass got named 'Circulo'. Then I had a hard time trying to create a protocol to 'host' it, but finally it got created as protocol 'a'. Initially it got created in the third pane in the browser, below without any apparent 'breakpoint hierarchy'. However, as soon as I wrote the method and got to save/accept it, something strange happened, namely, 'brakepoint' protocol was created out of nothing , and my 'a' protocol was put under it. The method itself in the fourth pane, has a red ! sign. If I right click on the method, and try to remove the breakpoint, it does nothing. What happens this and how can I have a normal situation , since I did not put breakpoints ? Thanks for your kind help
