I need to correct something I stated earlier. Regarding the two breakpoints that get created for a single “toggle breakpoint” invocation, either one of them could be the non-functional breakpoint. Sometimes it is the first one, sometimes it is the second one. The indicator as to which one is the non-functional one to be deleted is the little breakpoint symbol that appears right after the checkbox for a breakpoint in the breakpoint list. If the symbol includes the little checkmark, then it is good — delete the other one. The one to be deleted will always have a symbol that is just a filled blue dot without the little checkmark.
